I WAS WONDERING IF YOU COULD PUT A 454 IN A 1987-1992 CAMARO

yeah, its not that hard, kinda tight though. The biggest problem is fitting in exhaust that flows well enough to support the motor, I think. Cause you get squeezed in pretty good where the manifolds bolt up. I think they have headers made specifically for that application now though.

http://www.oldwestracing.com/cars/willallen.htm check that car out. Hes from around here. The times at the bottom are OLD...he runs 9 currently and is looking for 8.90s this year. Its a 472, but still a BB.

why not just a firebreathing small block?

same or similar power, lighter, and less hassle to install.

i realize the novelty of it, but i honestly think it would be badass to say you have a 427 or a 454 small block!

Big blocks have more potential - period.

The cost of a "firebreathing small block" would be similar to that of a BB.

There really isn't much hassle at all. They bolt right up to existing SB transmissions, they fit decently in the engine bay, companies already make exhaust components for this specific application. Accessories are no more hassle than an accessory system on a SB. It will bolt right up to the existing motor mounts. All that is really needed is a cowl hood. Almost no fabrication required.

And personally, I'd take a 427 or 454 BB over a similar sized SB any day. Why? BB's are more effecient, and the aftermarket is better for high end components.

small blocks are cooler for one.

and if u have a big block people expect you to be fast.

It's all on my page at www.koolmeister.com I did the swap almost 6 years ago.

if youre building a strip only car then yes bigger is better and drop the biggest rat motor in there that you can find.

However if this thing is seeing street duty or even street/strip you can make more power in a 427 sbc then you could ever hope to put to the ground, an sbc is lighter, and with strong enough internals can make pretty much about as much power as youd like.

And to people who want to cry about how bigger is ALWAYS better tell it to my friends dad who bought a C4 vette, pulled the V8 out, put a V6 in and turbo charged it. Oh btw this car is 100% street legal smog and everything and runs consistent 9.7x's

Although you can build a strong or large SBC, it's easier to make power with a BBC. Unless you buy some very exotic SBC heads, heavily worked over SBC will only flow about as much as relatively stock BBC heads so right out of the box the BBC has better heads to work with. My engine only uses 2.19/1.88 valves but I should have had 2.30/1.88 installed. It's hard to get large valves like that for a large SBC engine without some very expensive heads.

The BBC with an aluminum intake is only about 100 pounds heavier than a SBC but the extra torque obtained from the BBC can easily overcome that extra weight.

Exhaust is the worst thing about the swap. Hooker makes the cheapest swap header but they're also the smallest and poorest fitting. Ed Quay, Sanderson and Lemons all make swap headers but they're full race headers. The Hooker's are more of a street strip. I have Hookers on my car because I got a good deal on them. I run open exhaust so I don't have to worry about an exhaust system. The cheap route is to use factory cast iron manifolds but they offer no performance potential.

As mentioned above, the BBC will bolt right up to your V8 tranny. Even the engine mounts are in the same location. needing the cowl hood depends on the intake/fuel system used. A low profile intake and drop base air cleaner might fit under a stock hood but then you give up performance with the poor intake.

You should consider upgrading the cooling system depending on how much the engine is built up. A 3 core copper rad is a minimum requirement.

BBC come in 2 sizes. Short deck and tall deck. The deck height is the distance from the crank centerline to the top of the cylinders. The tall deck is .400" taller. Using a short deck block the biggest displacement available is 540. It has the same external dimensions as every other common BBC, 396, 427, 454, 502. Getting into a tall deck block can build some very big engines but also creates a lot more problems with clearance. Building a 632 is nice but you're not going to use 1 7/8" primary tube Hooker headers on it. A 632 with 10:1 pistons could easy make 700 hp on 92 pump gas without having to use a power adder.
