I have a lo3 motor and I plan on swapping the following:350 4 bolt,forged crank,pink rods,crane compucam,and keep my tbi setup with a custom chip. My question is I would like to put a Crane Compu Cam in the motor that is for a carb car because the cam has a higher lift, and slightly longer duration (LSA 112). If i get a custom chip burned will I be able to use a compu cam for a carb with my TBI?

 

as long as you use a custom chip you shouldnt have any problems (what intake and heads are you useing?)

 

yep scott is right

and what sort of cam and heads are you planning on that need such a strong bottom end?

 

TBI is good for our kinda engines. But personally, if I went something over 350hp I would go with carb. I mean, you don't see today's cars with TBI still on them do u? And no one better bring up anything about trucks with TBI because I don't care. We have firebirds, not 454 Trucks. So if I was you, and you think your 350 is going to be putting out big numbers, save yourself the money and time espically and convert to a 650cfm or whatever cfm carb and just do the swap. Cause with TBI you never know how things are going to run. With carb you will after the tuning cause if thats what the company that made the engine dynoed it with then that must be the best injection system for that engine. Makes sense to me.
