cam question

July 24, 2005

recently acquired a 350 and 700r4 out of an 88 Suburban. the engine seems to be in decent shape (4 bolt with TBI), but I wonder about the cam setup and am not sure where or how to find specs on it. It's a "Mr. Goodwrench" crate with 21K on it and I wasn't sure if the cam would be akin to something out of a truck = low end torque and needing a swap for my z conversion.

How can I tell? What can I do? any input would be highly appreciated. I'd like to just drop this whole thing in and start driving.

stock TBI cams are designed for emission compliance, fuel ecconomy and smooth low rpm torque, and to work correctly with the sensors controlling the TBI (injection) NOT max performance, if you keep the TBI and matching computer controls youll not have a great deal of room to get a more radical cam to work correctly with the stock computer controls, now you CAN reprogram the computer parameters but the TBI does not flow a great deal of air and its restrictive at the upper rpm range.

you really should get these books and read them before going any further, it will help a good deal, while only the basic info is presented it still makes for a good knowledge base, and referance its almost a 100% sure thing youll waste time and money if you don,t

DO YOURSELF A HUGE FAVOR

buy these books, FIRST it will be the best money you ever spent, read them, and you will be miles ahead of the average guy. youll save thousands of dollars and thousands of hours once youve got a good basic understanding of what your trying to do!
