350 Holley in astron

[Chris84gsr]

Ive been searching and searching can someone lead me onto a couple of links on putting on a 350 holley to a 2.6ltr astron, im really interested in doing this if theres no topics on it can anyone tell me what else i need apart from the 350carby and adaptor plate, thanks and if anyones got any of that laying around or some extractors i can pick up im looking at cheap ways to gain a bit more power since im only on my Ls

have you compared a 350 Holley to a small weber?
the Holley will win, hands down, every time.

350 holley 2bbrl's are TOO big for standard astrons and saturns, turst me. maybe on a wild stealth built astron but otherwise useless. mate had one on a gemini 2ltr and was way to big would flat spot everywhere no matter what jets/power valve/pump shot/pumpshot cams, we tried. go a 34 adm weber, they are the ducks guts pron with the 350 holley's is both butterflies open together.

should work... maybe ... no worse than a single webber sidedraft, which work when choked/jetted correctly, might have to spend the cash on a proper dyno tune with someone who knows Holleys though...

I was also thinking of trying a 350 Holley, maybe highjacking here but the manifold I have acquired is off a GN Sigma. Is that a good manifold to use of are there better models? My head is M4.
Cheers,

If you are determined to go Holley the Holley 390cfm (4150) 4-Barrel Carburetor would be a much better option than a 2-barrel 350, especially on a stock to mildly worked engine, in my opinion.

I've seen rebuilt ones go for around $300 delivered.

It would take a bit to tune, just like the 350 will, but I believe the end result, even on the stock engine, would be better.

Cheers.

oh yeah the 390.. "Mini Muscle" i always forget about those

pity you dont live in tassie mate, we have one of the best holley tuners in the country here
