Thread: 454 in a kingswood, will it fit under the bonnet without needing to protrude?

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.

HQ GTS Coupe rebuild number 2

Cheers Mario

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.

Here's one that was on ebay that fits under.

Ash had a BB in his HQ coupe under a standard bonnet with filter if i remember?

First image - under with bracing trimmed
Second image - out.

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.

Why Peter?

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?
