what cam with the TBI ? the gm cam.. any thing bigger just plain will not work .i went roller on the last one as the customer had a roller block so like i said i had a very small custom cam that would work. go carb you can make it take more cam . the old tbi are not very friendly to work overs. some guys have gone up to the 454 main body .moving up to a 383 with a stock cam with 1.6 rockers may work out good . i know many guys tried bigger cams.i never seen one that would work good

I wasn't planning on using the stock TBI i was going to buy a performance so if going carb is better ill go that way
