Ok guys, I got me another wild hair and decided to do something I'll most likely regret again......humor me!
I've a whipple sitting in the passenger seat, and an 11:1 CR LT1 from a 1970 sitting under the hood. Now those engines came stock with a Holley 780cfm double pumper(although it currently has a 750 DP mechanical secondaries on it). So, realizing I'll need to detune the engine to even properly use a 454 tbi(~600cfm in stock form)....here's the question, what would you do? and here's the limitations to your answers: a tbi from a stock engine(can be modded ofcourse: mods, injectors, etc?), no major engine changes(eg: no I'm not swapping to a tbi modded LS engine LOL), parts changes allowable are: valvetrain, intake system, & heads(limited to what I have on-hand: 462s, 461s, and some modified mid-70s truck heads with large runners and 73cc chambers); retaining the stock-style 2500 stall.
The whipple is an 1100cfm.
Current engine uses 3-layer copper head gaskets; switching gaskets with different heads is a viable option. Also have a new set of pistons from a 73 LT1, which was ~9:1 CR.
Also, I can change pulleys on the whipple, no problem there.
