Hey everyone,

I finally got around to my engine build up. I am building a 355 TBI motor. The cam is what I need some help on. The man at the machine shop gave me some cam specs and I need some input on if it is going to work with a stock computer or what I am going to need to do about getting a chip burned. Any who! Cam specs are,
224 @ seat/224 @ .050/ 495 Lift. Also 222/222/475 to 500. I am going to be running heads off of a 350 TPI car, Carburator intake with TBI adapter plate. I was thinking about using flat top pistons to up the compression a little, any feedback on if this is a good or bad Idea would be great as well.:hail:

I'll be surprised if the car even idles with either cam without lots of chip work. I'm runnin a 218/226 462/480 cam and it took me 2 days to get it drivable. Even then I'm barely able to feed my motor with 75pph injectors cranked at 22psi to 110pph each. So in a word "NO" it won't work. You can try a mail orderchip but you'll just end up wasting time and money. Your stock TB will choke your motor too.

Thanks for the info, Well can you suggest the best cam for use with minimal Chip changes, with the setup that I will be using. Also, I am interested in burning my own chip but don't know if it is worth my time. Tell me if it is a good investment or would it be cheaper to hook up with someone who already does it!!

Thanks
Dean

None out there. The stock tune becomes way off as soon as any mods are added. The stock tune is really that bad. You are going to need to add chip burning stuff to your parts list. Also, i would get the heads machined so that you can run larger than .480" lift.

my cam is going in next week hopefully. my first mild cam swap and engine mods resulted in a big need for tuning. like car would not run period. now i have some knowledge(basic) so i believe i can tune around the bigger cam. my LSA is 114. what is that cam LSA? consider tuning B4 you do the swap. you will need to sort out the basic day one tuning nightmares that we all experienced getting started. after that done no reason why you can run a larger cam.

Crane Cams makes some pretty weak camshafts that are suppose to work with the stock tune but im not sure if they actually will. One has a duration of 184/194 and the other 194/204, and both have intake lift alittle below .400" and the exhaust is alittle above .400" with 1.5 rocker arms. And they are pretty expensive, they run about $260.

i have the crane computer cam 2040. 210/216 @.05, peak power at 5000 rpms. not sure if it will live with stock tune. i doubt it.
