.justin. Posted December 21, 2007 Report Share Posted December 21, 2007 Comp cam has recalled all 918 springs with batch numbers listed below. Call Chris Mays at Comp Cams at 901-795-2400 extension 505 or [email protected] and they will next day updated springs. I just installed mine 3 month ago batch #049045. They will be coming out shortly. 1) 49253 2) 049045 3) 49826 4) 050808 5) 051791 I assume this information is printed on the box, right? I'll have to check mine out when I get them out of storage in the next few weeks. Quote Link to comment Share on other sites More sharing options...

I thought i would get very little use out of my Crane Cams spring compressor. Guess i was wrong.

misterp Posted December 21, 2007 Report Share Posted December 21, 2007 Just came back, it is a spring that broke and the valve is broken in two and all the parts are stuck in the head...the piston has the side of the valve nailed in and the cylinder is marked pretty bad. I think I'll need to oversize but don't know how much. how much oversize is needed for a 370 and for a 408 and what kind of piston or overhauled stuff I need? So sorry man, hate to hear this. I guess it could have been worse, at least the block is still in one piece. Mr. P. Quote Link to comment Share on other sites More sharing options...

detjoe Posted December 21, 2007 Report Share Posted December 21, 2007 thats what I dont get, is it a batch thing or not?? B/c I think alot have blue stripes, but my batch # is no where near what is listed?? It is a PITA to swap these, espically if there is a zero gain (not going any faster) Quote Link to comment Share on other sites More sharing options...
Simon Posted December 22, 2007 Author Report Share Posted December 22, 2007 Yes I have a blue stripe on them... About the motor, it's gotta be more powerful for sure but it is still my DD so I don't know if 408 is too much. Is 383 possible? I guess anything is since i'll be doing oversize and can buy the pistons for it... and maybe rods...if they are bent... Quote Link to comment Share on other sites More sharing options...
detjoe Posted December 23, 2007 Report Share Posted December 23, 2007 go 408. Quote Link to comment Share on other sites More sharing options...
kelleyperformance Posted December 23, 2007 Report Share Posted December 23, 2007 damn man, sorry to hear about this. i broke a valve spring a few weeks back, but it was just one coil off the top, so i just get a little misfire lol. (i should prob fix that LOL). id go 408 for sure.... good injectors and good tune it will run just as good or better than what you have now. of course it will get signifigantly worse economy tho.

detjoe Posted December 23, 2007 Report Share Posted December 23, 2007 how did your mis show up-flashing cEL or a steady on one? I hate worrying about my truck. Quote Link to comment Share on other sites More sharing options...
kelleyperformance Posted December 23, 2007 Report Share Posted December 23, 2007 nah the solid misfire CEL is disabled, the flashing one shows up. but my exhaust makes it nice and easy to hear a miss, so i heard it before i saw the light. it does it all the time, but this makes me not wanna put comp 918s in Quote Link to comment Share on other sites More sharing options...
detjoe Posted December 24, 2007 Report Share Posted December 24, 2007 shit-I just found the pic from when I did my swap and they are blue striped should I change them? and I too then would not want to put them back on??? $200 down the drain Quote Link to comment Share on other sites More sharing options...
Simon Posted December 24, 2007 Author Report Share Posted December 24, 2007 If i knew before, i would have changed them...look at me now! Quote Link to comment Share on other sites More sharing options...

Simon Posted December 25, 2007 Author Report Share Posted December 25, 2007 (edited) Gee, how come I was sold that at the same moment than my cam with 591??? edit, I just found they are rated at .600 lift max, quite close to what I have Edited December 25, 2007 by Simon (see edit history) Quote Link to comment Share on other sites More sharing options...
