hey mark,
a few posts below u mentioned a 350 holley feeding your 2ltr donk is it a sohc? and if so what fuel consumption do u get? (k's to a tank) (just out of interest)
cheers

I always run 350 holleys on geminis. They work better than any other carby/carbies ive ever used. I was running twin 40mm sidedraught webbers on that 2 litre and made 120hp at the wheels, a 350holley on a standard manifold made 138.9hp.
Ive run about 5 cars over the last 3 years with 350s, from a mild 1800 to the full house 2 litre sohc ive got at the moment. It generally gets about 300km to a tank, but not really sure how empty that is. I look at it as 300km from $25

hello Mark, just wondering what size valves, what brand camshaft, how much compression and how comprehensive the port work is to get that figure, depending on how much you want to give away.

would that work on a mild 1600 wif about 110 hp??

[Mark]

No mild 1600 has 110hp!!!!!!. Ive never run one on a 1600, so i dont know. I assume it would work with a large cam 1600, but a mild one....it would prolly be too big.
The motor that had 138.9hp at the wheels is a standard rebuilt 2 litre, double row chain, flycut pistons, lightened fly wheel, shaved 1600 head, crow springs and crow 425 thou lift, 288 degree duration cam, standard large valves ( 42.1, 34) and I did the port work myself. Its about as extensively ported as i could manage.

hey mark the 1600 has 80 thou off the head 43mm inlet valves port and polish 60 thou oversize pistons in it and a 105hp @ flywhell at 6000rpm

hey mark,
what manifold did you use, standard or something else.

[Mark]

standard non pollution manifold, cut out to suit the adaptor plate size then port matched to the head.
