pool 12-24-2006, 03:24 PM I need to know if a late model 454 will fit in a 1977 elcamino It would not fit in my 80 how do I make it fit?? i spent 9 grand on this engine build PLZ HELP CoyoteOn2 12-24-2006, 07:08 PM -------------------------------------------------------------------------------- I put a 454 in my 77, and the only mod was the ac box, took lower right corner off it for valve cover clerance. There are some picts in 4th gen, page 8, bottom center. theelcaminofactory 12-24-2006, 08:47 PM It would not fit in my 80 Let me guess, your using a tall deck 454 and being that you spent $9K on the motor your running full roller rockers with tall valve covers and it's hitting the AC box. You could put an AC/heater box delete plate in there and then it should fit. This is a common problem when using a Gen V or VI 454, it's not a problem when using a Gen IV 454 as long as you don't use the tall valve covers...which means the best you can use is roller tip rockers...which will clear the stock or low profile valve covers...or you could always modify the AC/heater box, but even then it's still tight. | ||
