Brunswicks SS Posted March 22, 2011 Report Share Posted March 22, 2011 Well fast4pooper suggested I do the l92 head swap with full cams and all. I just wanted to see who has it done and what you think. My goals are around 550hp and 13 flat in the quarter mile. I have about 2500 to spend. I have other monry for tune and tranny work. What would you guys do? Quote Link to comment Share on other sites More sharing options...
silverado777 Posted March 22, 2011 Report Share Posted March 22, 2011 That swap can be done and I have seen them put down some good numbers. Are you looking for a stock swap or are you looking at springs, lifters, pushrods, and rockers as well? $2500 will get you a stock swap.....maybe Quote Link to comment Share on other sites More sharing options...
The_aSSet Posted March 22, 2011 Report Share Posted March 22, 2011 , cam swap with springs, pushrods, injectors is like 1500-2000 depending on if your doing the work or someone else, and l92 heads and intake its really about who's selling them and how they're sold, bare = can be pricey (to get all the stuff for them) ported&polished the whole nine yards = big money, from like 1000-2000 for a pair stock = budget, u can get stock assembled heads for like 500-800 from what ive seen l92 intake is probly the cheapest theyre pretty commonly sold for around 100 Quote Link to comment Share on other sites More sharing options...
Brunswicks SS Posted March 22, 2011 Author Report Share Posted March 22, 2011 Well my phone isn't letting me post a link. Its on the slp site its 2800 with heads intake manifold and cam. Basically everything and can get it 2100 with out cams. If some one can post the link it would be cool. Quote Link to comment Share on other sites More sharing options...
silverado777 Posted March 22, 2011 Report Share Posted March 22, 2011 http://www.slponline.com/view_product_site.asp?P=12292&BIG=12292-1 Don't for get you still have the cost of cam, push rods and lifters. Not to mention the cost of this install kit. http://www.slponline.com/view_product_site.asp?P=12507&BIG=12507-1 I think total you are looking at $3000 - $3500 total Quote Link to comment Share on other sites More sharing options...
2bfast Posted March 22, 2011 Report Share Posted March 22, 2011 Basically everything and can get it 2100 with out cams. Since when did LS motors grow another cam? Quote Link to comment Share on other sites More sharing options...
Brunswicks SS Posted March 22, 2011 Author Report Share Posted March 22, 2011 Since when did LS motors grow another cam? Ha been a long day. Spelling isn't the first thing on my mind. Yeh the install kit and injectors would need to be added that's why I said I have other money for that. I'm saying just for the kit around 3000 and yes me and a friend would be installing it. I saying for my goals is this a reasonable kit? Quote Link to comment Share on other sites More sharing options...

shadowsniper3006 Posted March 23, 2011 Report Share Posted March 23, 2011 (edited) The l92 swap is really starting to look appealing. The more i look into it, the more i like it. Check out detjoe's thread about his l92 swap, its a very good thread for your how to, the parts needed and one way to do the fuel system. http://www.totalengineairflow.com/products/gmhead/gml92/ if i was looking into the l92's i would use these as my benchmark for comparing. When comparing don't just look at best flow number, look at the numbers all the way up and what size valve/runner they used to get those numbers. I've seen a bunch of heads post the same flow numbers but they had to use a larger valve to do it. From what i have read, it looks like MAST has a good l92 head as well. What ever head you go with, make sure you maximize the compression with the chamber. Compression is your friend for a set up looking to run 13.0. Talk to the guy selling the head and find out how much they can deck them. When you get that number, figure your compression with a .041 and .051 gasket to see where you fall. I wish mine was 12.1, it would make things easier. Don't get caught up with big cams, they make power but the low end loss isn't worth it. I would have rather made my time with torque in the first 60 feet then run the 4500 converter i have. And i would rather shift at 6600 then shift at 6900, which still isn't high enough. And i would rather run valve springs with less open pressure then worry about the wear on my cam bearings and the life of the spring being 20,000 miles or less. I ran a 12.8 on a 224 cam and less compression. From what i have seen so far, my 224 needed a 3400 stall to really hit. I have seen a 230 cam need a 3500-3600 to really hit, but he was running mid 11's for compression. My 235 cam needs all of 4500 with mid 11's compression. The cams LSA and many other factors effect this but it gives you an idea. You don't need these high stalls but if you want a run for the 13.0 range, you will need to match your cam and stall. Don't skimp on the heads the extra money spent now will be worth it later, and don't fear a large runner. If you can get a larger intake and exhaust runner and still deck the heads enough for compression, watch this as with larger runners you have larger valves and larger valves with decked heads can put the valve into the piston real fast, then do it. I wish i had a 235 runner on my truck and most put a 215-220 on. One of the best l92 set ups i know of is Skeet. PM him and may be able to send you better info on the l92 build and what he has learned for picking cams and the stalls required for them. Don't forget headers. A 1.75 will get you there but a 1.875 will help more and give you room to grow. I would start out with the l92 intake, the truck intake. Not the ls3 or l76. The truck intake will help with 60 foot times and shift points. Ls3 hollow stem valves are nice for better valve control, better valve seat life and for less spring pressure, but if your cam is tame enough they are just a plus.

hottelboy Posted March 23, 2011 Report Share Posted March 23, 2011 (edited) Joes build is very helpful, don't forget also the miscellaneous cost like DR. X $225,vette filter about $50 and VALVE COVERS $100-$400 the stockers will not clear the offset rockers on the fill side. Depending on miles on your truck the timing set(mine has 90k and was stretched like crazy)engine cover, fuel line, gaskets. Just to name a few things.

detjoe Posted March 23, 2011 Report Share Posted March 23, 2011 hey Brad. glad to see you post (hint this guy has gone fast ) I want to change my fuel setup, I am liking the new aeromotive pump that will fit in our basket and some 60's. I hope to better my PB this year. Quote Link to comment Share on other sites More sharing options...

This is a -decent- upgrade kit but I dont think would give me the wow factor for the money and hassle. This is my opinion - If budget was not an option, I would go w/ Trick Flow or PRC heads, if budget was in mind to me trying to swap to L92 setup is more than a set of worked 317's and cam to match. OR LS6 heads. At the end of the day, it all depends on what your future plans are for the truck. To me to convert to this and DD it to make decent power is useless Again.....my opinon thinking about you budget guys Quote Link to comment Share on other sites More sharing options...

12'SROCK Posted March 23, 2011 Report Share Posted March 23, 2011 You can get 13.0 flat or pretty dam close to it without heads. My truck ran 13.4@102 with a 2.06 60' on a shitty track. I have full boltons and a cam. I had a very very tight TC and couldnt 60' fot the life of me. With a decent converter I guarantee I would have been way faster. I like the cathedral port style heads. I am not a fan of the L92 set up. Either way good luck with yout build. You are heading in the right direction Quote Link to comment Share on other sites More sharing options...
