Thread: bbc into camaro?

Tweet

i was wandering what problems i am going to run into when putting a 454 into a 78 camaro with a 3in. cowl that currently has a 350. i already have big block springs in front and a turbo 400. thanks

You should have some frame ties and maybe even a 6 point roll bar to tie the car together. What rear end do you have in the car? If you get the chassis stiffened up and a tire that will hook the rear end becomes the weakest link....

the rear end is stock for a z-28 it is a 8.5 in. 10 bolt open diff. i need to get a posi or something of the sort but keep in mind its just a daily driver that i like to have some weekend fun in. i was wandering about motor mounts and where to get headers?

I believe Hooker makes headers for the swap, did one a number of years back and I believe that is where we got them. I'm not a chevy guy, but aren't the big block and small block mounts the same? If I'm wrong, I'm sure the chevy guys will let both of us know... I think I also had to do some modifying on the firewall to get the HEI cap to clear, or maybe I moved the motor back a bit to move some weight rearward. It was a lot of projects and a few years ago so excuse my CRS......

Both Moser and Currie make a bolt in 9" rear end for your Camaro. As long as you leave it a one wheel wonder I doubt it will hook up enough to break the 10 bolt. I've seen them 8.5's take a lot of abuse even with a posi in them....

i installed a BBC 454 In my 76 Camaro with no problems,
if ur looking for somethin good headers get the Hedman Headers (#65001 ) for painted or (#66105) for ceramic coated and if ur looking for body mounts buy a Polyurethane from Prothane (#7-139) and if u wanna see and feel a big different in handling and looking buy a Hotchkis TVS Systems (#80016 ) its a suspension pakage and its great!!

I don't have any stock stuff in the original spot on mine anymore, but the valve cover might be a little close to the brake booster. I think a mini booster may clear. But don't take my word for it cuz' it's been a long time since I've seen a stock 1.

Either a bigger radiator or no inner fender wells, I ran a 455 olds in a 78' camaro with the stock 305 radiator that way, of course money was a factor.

will these headers work on a pair of 781's?

Sean!
Make Sure Your Primary Pipes Are Larger Than Your Exhaust Port Diameter, And That The Header Flange Doesent Protrude Into The Port Pathway.you Can Clearence Any Protrusion W/an Diegrinder & A Little Finesse, Try To Get At Least A 3" Exhaust System And You Will See A Huge Improvement In Power.
