My winter project. Hope to start by May.

Cool! What exactly is hybrid about it?

soupcan

Sweet.

hacker-pschorr

Hybrid = 16V top on a 32V (5.0) lower.

What compression ratio did you build?
What lower end is that?
What EFI are you running?

DETAILS MAN, WE DEMAND DETAILS!!!!

Lopez,
5.0L short block, 16v USA heads.

Hacker,
9.7:1 CR. Pistons have been dished and ceramic coated. 1985 short block. Using L Jet.

My car already scares me...so I can't imagine what yours would do to me. I'll bring my own platic seat cover when you take me for a ride.

hacker-pschorr

I'm assuming you started with 85/86 pistons then?

L-Jet??? We need to have a chat.....

I'm starting to put the details together on a similar project. I recently aquired all of the parts, now it's assembly time:
S4 lower end (swain tech coated pistons)
EuroS heads / intake / TB (swain tech coating on combustion chamber & valve faces)
78-79 Cams
Maybe a custom intake manifold, not 100% sure yet.
LH / EZK
Boost level to be determined. No less than 20psi

toofast928

I'm only gonna run 8-9 # boost. L Jet should be fine with BEGI help. Next year the plan is to convert to MAF.
Wait till you see the air filter set up................

86. Unless you didn't use the one I sent you.

You could run 30psi if you used the right fuel.

You sure you won't lose 50hp with that crank pulley?!?!

hacker-pschorr

The only thing keeping me from running 30psi now is my supercharger. We'll see, if I'm able to hit 500rwhp with the new motor and my current blower, I'll leave it.

Wait a minute, did you ever check pressure before the barn door? I've got to think that your bottle neck is the barn door, not the SCer.

That's Gorgeous! The light gray really looks good.
