SRT10KLLR Posted November 11, 2006 Author Report Share Posted November 11, 2006 Here is a pic of my other truck. It is a 2005 Ram 2500 RCSB ThunderRoad Hemi Sport. They don't make that here either. lol. First, they don't make Regular cabs in 2500 or in a 5 lug. Secondly, the Hemi Sport is only sold as a quad cab here(reg cabs with that spoiler kit were called Rumble Bees here Yellow/Black). Lastly, it have 5 leaf spring like the 2500 vs 4 for the 1500 here. But all that doesn't matter because what does matter is the fact the the pink slip says 2500 RCSB so gthat is what it is. BTW, they make Cadilac in a pickup truck there also and it is not the Escalade, Excalade ESV or Escalade EXT(those are also sold there). It is a RCSB with the front of the Cadilac, dash w/gauges, door trim etc. and you buy it at the Cadilac dealer and it is titled/registered as a Cadilac. Many other countries sell vehicles we don't sell here. Quote Link to comment Share on other sites More sharing options...
Black2003SS Posted November 11, 2006 Report Share Posted November 11, 2006 Give the guy a break would you guys? He's asking for some help, help him. If GM builds a truck and puts SS on it, its a GM SS, maybe in a different country, but still it is. At least he didnt buy a nissan or toyota. Maybe its not what we are used to, but let it go...geez. Remeber what people say about our SSS's outside of GM? Alot would say our trucks never deserved the SS badge either, even if we can make them 11 and 12 second monsters. Even some TBSS guys would call our trucks worthless. Humbleness is a great virtue gentlemen. As far as stroker kits go, the 5.3L block can go up to 427ci, possibly more. Lunati seems to make some of the best forged stroker kits out there. The most common stroker kit is 408 ci. You would probably do better to ditch the 5.3L and find a used LQ9 or LQ4 6.0L block and start from there. SLP makes complete 402ci short and long blocks in both low and high compression ratios. You can find stroker kits at tbyrnemotorsports, slp, summit racing and many other places. Also, do a search on here for stroker information. Benkey has built a very nice 408 N/A stroker and adapted an LSx style manifold to it. Quote Link to comment Share on other sites More sharing options...
SRT10KLLR Posted November 12, 2006 Author Report Share Posted November 12, 2006 Black2003SS, thanks I did not know the 5.3 could go that big. I had read you could use 5.7 pistons but I did not know you could make it a 427ci. What would be the benefit of using a 6.0 block if the 5.3 can also go 408?

Black2003SS Posted November 12, 2006 Report Share Posted November 12, 2006 The reason to use a 6.0L block is because they already have a bigger bore and require much less machine work to punch them out. The 5.3L block has a bore x stroke of 3.78" x 3.62". The 6.0L has a bore x stroke of 4.00" x 3.62". So just by changing the stroke on the 6.0L you will gain alot of cubes (402ci). With a .030" over bore, that would put you at the 408ci mark. I'm not 100% specific on what you need to have for the 427ci. I think its bore x stroke of 4.125" x 4.00". Not positive though. A 402/408 will produce in excess of 500-600 crank hp with little effort and daily driver capable. With wild cam and heads, you can exceed those numbers. Either way, you will want to look into a 4L80 trans upgrade if you go that big. Especially since your truck is 2WD already. Don't waste the money on an FLT level 5 trans, spend the extra $1k or two to swap trannies. Quote Link to comment Share on other sites More sharing options...
trickmob Posted December 17, 2006 Report Share Posted December 17, 2006 If I wanted to make my lq9 a 402 what kind of machine work would i have to do.What do I need to do to make that fit Quote Link to comment Share on other sites More sharing options...
Professiona1 m0d Posted December 17, 2006 Report Share Posted December 17, 2006 (edited) Trickmob, you could actually do a 402 CID motor with just honing the cylinder bores (you actually do not need to over bore them and pay for that expensive machine work). Then you just get a different crankshaft with at least a 4.000" stroke. Essentially all you are doing is stroking it. You can make a LQ9 to a 402 CID motor fairly cheap and easily. Hope that answers your question. Edited December 17, 2006 by Professiona1 m0d (see edit history) Quote Link to comment Share on other sites More sharing options...
trickmob Posted December 17, 2006 Report Share Posted December 17, 2006 when I drop in the crank do I need to machine the block for it to fit Quote Link to comment Share on other sites More sharing options...
Professiona1 m0d Posted December 17, 2006 Report Share Posted December 17, 2006 You shouldn't need to machine the block at all to make the new crankshaft fit. That's the beauty of it. Quote Link to comment Share on other sites More sharing options...
trickmob Posted December 17, 2006 Report Share Posted December 17, 2006 Can some one tell me for sure.I think I might do the stoker 402.Do I have to pull out the motor.How long do you think it would take a dealer with the right tools to get the job done.

Professiona1 m0d Posted December 17, 2006 Report Share Posted December 17, 2006 No modification needed for the crankshaft, however, it is recommended you hone the cylinder walls. Yes, you do have to pull the motor, dissassemble it (remove the heads and etc...), and then rebuild it. As far as how long something like that would take it completely relative to the engine shop/guy. I've seen it done as little as a week (all the parts where on hand) and as long as a month (ran into part problems, back orders, etc...).

trickmob Posted December 17, 2006 Report Share Posted December 17, 2006 Thanks for the info.I got the money, now I just got to pick an option Quote Link to comment Share on other sites More sharing options...
SRT10KLLR Posted December 20, 2006 Author Report Share Posted December 20, 2006 I came accross a LQ4(iron 6.0) for $600 plus $200 for the heads if I want them. Is that a good deal? Should I use the heads as is or have them p&P? Would there be any benefit since I will be runing 15 psi? What intake would you guys recommend?

Professiona1 m0d Posted December 20, 2006 Report Share Posted December 20, 2006 (edited) First off, that is a pretty good deal. Secondly, you definitely would see a gain in porting and polishing those stock factory heads. One thing though to always remember with forced induced motors, you will never see gains as high as you would if you did that to a naturally aspirated motor. Also another thing, you will lose some boost, not that much though. It definitely would be a powerful motor. Keep us informed on how it goes! By the way, as for intakes, someone else will need to answer that one for you. Don't know all that much about the aftermarket ones other than the FAST LSX intake.

SRT10KLLR Posted December 20, 2006 Author Report Share Posted December 20, 2006 What would be better(best bang for the buck)? 1. P&P the 5.3 heads 2. Buy the 6.0 heads and have them P&P 3. Buy some P&P Edlebrock heads for $2300 - Flow 330I 250E What is a good price for P&P the heads? Quote Link to comment Share on other sites More sharing options...
