454 in a kingswood, will it fit under the bonnet without needing to protrude?
Hey guys, been trying to do my research on finding out details on putting a 454 in a kingswood, will it fit under the bonnet (All the pictures i can find are obviously bonnet up or have superchargers through the roof) without needing to purtrude? Should be fine as far as the rest of the conversion goes but i just want to make shore she will fit under the donk before i buy the motor.

so by ya name ya talking about a HX? a donk is a motor not a bonnet btw and it depends on what manifold you run! stock low rise yes and a torker 2 but anything else is gunna need cutting

I have a BBC in a HQ it came with a dual plane intake and I still had to cut a hole in the bonnet to fit an air filter

Here is a whole build thread and InjectedQ's HQ build with BBC under std bonnet. Lots of reading but it's in there somewhere how he did it.

I had a factory 4bbl manifold, 1 inch spacer, Holley and dropped base 2in cleaner...under but bonnet bracing removed in that spot.
Have just replaced it with dual plane Weiand 8005, no spacer, same Holley, same cleaner, she's out by couple of inches, but have a read of the above thread and how it can be done.

When mine was on ebay it was the same pics with air filter etc etc, but when I actually saw the car he removed the air filter I said where is the air filter he said in the boot, the bonnet won't close with the air filter on.
I tried my mates 1" air filter and it still won't close and that without running a spacer as well.
Ash is the only one I have seen that can do it, but he used a wok lol

Victor Jnr manifold, 1/2" spacer. 4" cowl bonnet:

yes, I had it under but it took some mucking about.
as was said, I used a Wok and an extreme top, but I had to cut bracing to get it under. read through the thread (lots of info) and it will all be there.

Why go BB? Slide one of these straight in Scott Shafiroff Racing Drag Race Engines & UltraStreet High Performance Pump Gas Crate Engines If you want a bit more power they do an 835 HP version.
There is also a Corvette low rise manifold available.

my 454 and T400 owed me about 4500 for over 500hp. it had impeccable road manners, was a delight to drive at 60-70kph, but when you sank the boot in at those speeds it was an animal.
tell me where you can get that out of a small block where it isn't a grenade motor with a gut full of gas?
