im working on a project plan for putting a 427 aluminum block engine in my 98 camaro. but before i go spending my cash, will the engine fit? im pretty sure it will but what conserns me is will there be enough room for the carbueter and its air filter assembly too fit, because part of the back of the engine is under the dashes in the 4th gen cars.

 

It'll fit. You'll need to do some "massaging" in areas but to answer your question...yea...

 

Wow, that'll be something when it's done!? I agree that a big-block will fit, but I'm sure it'll require quite a few man hours!!! (and lots of beer!!)

Keep us posted on progress if you do this. Should be interesting.

 

427 smallblock? Easy.

BBC, right?

BBC (or SBC for that matter) with decent single plane intake and carb + filter, and standard distributor will probably get in the way of some body parts, and require a hood scoop/bulge.

A SuperVictor SBC single plane is just about the same height as an LT4 manifold, but adding a 1 inch spacer, carb and filter is another 6 inches or so. BBC is taller yet.

I do like the idea, however.

 

Hmm, World Products 427 SBC.

I would imagine you could limit some of the height problems by going with something like a Vic. Jr intake and converting it to EFI.

 

well it will be a 427 bbc 4 bolt main. basically what i am trying to accomplish is too build a 1969 zl-1 camaro but in a new 4th gen body. basically i want the 427 to have the same specs as the zl-1 from 69 also i will be using a 4 speed trans like the 69. but if its too tall then what can i do really. i guess ill try to make it similiar as possible with the 427 sbc.

 

i thought the old zl-1's had cowl hoods anyhow so i wouldnt worry about doing that to it because it will be more accurate with the cowl on it anyhow. as for the specs being the same i wouldnt worry about that either unless you really want to for sentimental reasons. if it were me i'd rather have better heads, intake, cam, etc we've come a hell of a long way from the ideas we had then over the last 30 years. not that i was alive then but my dad is amazed by my ideas constantly because he knows how it was when he was into it heavily. anyways to get back on track. as for making it fit i might talk to some of the guys that are making the aftermarket k-members for these cars, maybe see if they would like to use your car as a prototype. i'm not sure but they could move it a little forward for you so the firewall wont be such a pita. its going to be a very tight fit and if i was you i'd look into modifying the front clip of the car a little (stretching it). that would give you a little more room to breath with the rad and the ac core. as for the brackets and the other things i would look to vintage air's new setup they had one for the sbc that was very close together and very neatly laid out, maybe they have something for the bbc now if you do this i'd check with them. just on another tangent here i wouldnt go with 427 just for novelty. nobody will be able to tell just by looking that it was a much much larger bbc. the other thing i would add is an aluminum block is probably gonna be very costly and besides wieght it wouldnt be much better but yeah i know you're trying to recreate something. just a coulpe of thoughts to chew on.

Can be done but it's gonna be a bit of a hassle. If I were gonna do it, I'd definitely want an aluminum block to keep down on weight, a shorter MPFI intake (LT1-like) to fit under the hood, and a coil-pack ignition. Tubular a-arms and K-member would also give you a bit more room for the header routing. Good idea with a custom headered small block build too as we've found out with my build.
OR, you could build a tall-deck small block to 470+ ci. Standard deck 427-454 ci combinations are also becoming pretty common and the parts are plentiful if you have the $$.

As much as a I love big blocks (especially the 427) a 7.0L LS6 would be MUCH better for the car

 

Who builds 454's anymore?

Not when you can just use a 502 or build a 534-555 ci big block 9.1L.

Build the 555, call it an LS6.

the GMMG 02 ZL1 phase 3 cars all come with 427 C5R motors rated at 600 hp. one dynoed a 509 with less than 500 miles on it.

If you need pics let me know I got a bunch.

 

It's completely do-able. Send me $50,000 and your "core" car. Wait one year, and you will have a really bitchin' 427 BB 4th gen "ZL1". Just tell me if you want that with fries. Or maybe we can superize your order and give you a 502.

For the extra 25,000 you better supply a 502.

 

He can have any size he wants for $50K.
