LT1 Single Plane: Underhood Modifications A couple people have asked how a single plane would fit under an LT1 WS6 hood, I took a crappy pic today after washing the car of the modifications to the underside of my factory WS6 hood for those interested in the conversion. I haven't repainted the area that was cut out, but you could do this for a more stealth look.
As far as modification, just where you see the hood modified at the back and cut out. I'm using the lower Z28/Trans Am airbox. I'm not sure if the taller WS6 airbox on the LS1's would fit.

Man that looks sweet. I wonder what hoods would work on a camaro. I would like to know for future Reference. So when I start my motor build i can already have the hood in place. Trending Topics

Looks clean and professional! I like the valve covers too. Are those bolt-on fittings for the breathers? And do they use the push-in breathers? Lastly, where did you get those?

Some people complain about the low end loss with single plains but they are nuts because it is an easy choice when you see what you'll gain up top. Plus with a 383 you have plenty of low end to spare good look with the setup looks nice.

Here's a little bit closer pic. I only have a 1.2MP digital camera right now but will have some 6MP pics soon.
The Valvecovers are Pontiac Racing perimeter bolt SBC tall covers. The bungs are welded in with a baffle for the breathers and the breathers are push in style. The TB is a Nick Williams LS1 90mm and the intake is a Super Vic converted by BRE, powdercoated, coated on the inside by Polydyn and ported by GTP to match the heads.

we are in the process of building an elbow that will accept a stock style TB and claer a stock hood. Should have details in the next couple weeks.
Will be similar to the one we build for the LS1
