Holley manifold

[4g54gemi]

Im just wondering whether it would be worth the trouble of making a 4 barrel manifold. I currently have a standard sigma one ported (PICS). Would it be worth 20-30hp if done correctly? Specs 2 litre, astron 2 head, mpt60 turbo 22psi, 390 holley blow thru. Any ideas would be appreiciated. Thanks.

which one would flow better or more even?

I don't know what the current status is with stealth building things for people?
PM him and ask...

Or are you looking at making one yourself?

Yeah Im looking at making my own. Im having trouble finding 4cyl holley intake manifolds on the net. Anyone got any pics they would like to share?

Thanks very much for that, great pics. What size are the runners 1 3/4 or 2" ?

nice manifold , but wondering if you raise the top of the port a few mill in the head and added some in the bottom to give an angled down entry to the valve and keep the carb runners the same entry angle (and obviously port postion ) that would make an awesome methanol intake for speedway where single carb rules apply

Jump on youtube there is a corolla in Peurto Rico that has a blow thru holley set-up on an astron and it runs low 10's.
