I know that my carbed 675HP/645TQ 496ci stroker gets ALLOT of seat time daily driving when the weather is nice....even more so since I put the complete UMI package on and she drives like a new corvette. On a good weekend Ill do a 200+ mile round trip with my 3.73 gears and TH400 cruising at 3500RPM and she wont miss a beat....along with that its a 10 second car...maybe high Nines with the ET Streets if I 60ft. I even get 10-12mpg if I dont get on her
I dont do much track stuff, mostly street racing and 50mph rolls on the back roads. Once I put on Vintage air later this year Ill drive her even more....I prefer a BBC...I have my own LS build going together now with nothing to put it in that will be a turbo build....mainly just for fun and dyno numbers. I keep thinking swap, but I just cant bring myself to do it
Build what you want....just know a BBC can be done reliably with big power and efficient when the COMBO IS MATCHED. My 2 cents.
I do have a FITECH EFI here waiting for me to toss on as well....that will be interesting to see how she performers all around vs my Prosystem 953cfm setup.
