Chevy Sprint/ Geo Metro/ Suzuki Swift. Super tiny with low rotating mass. I think it requires machining of a custom pulley.

BTW, I'm racing my 1200 at Mission tomorrow.(Saturday) Just an invite to any local fellow 1200 freaks in the area.

I live in Delta. (next to Surrey) Can you get me contact info?

Mount Shasta, in California, is the biggest Datsun meet I know of. They do it every summer. Try looking up the Norcal UFO club for details.
I too have an old 1200 GT5 car. It competed mostly in the Oregon SCCA region. Sovren, the local Vintage club which I know of doesn't allow it yet as a vintage class car. I will be preserving it for the day that it does though. It still has all steel panels, and non tube structure.

ddgonzal,
Actually, gears are something I lack. I'd like to build up a serious revving engine, but cost prohibits.
A close ratio trannie and all the treatment to the engine required is too much to justify.
P.S... I'm looking for some trim bits.
I tried to contact you on P.M., but I think it failed.

Okay, so what if the torque doesn't double when they double the rev's?
If you rev the engine twice as many times, the torque is applied twice as many times.
That is what makes new F1 cars faster than old ones.

ddgonzal,
I'm in your area, and looking for info on some parts which can be sourced around us. Email me for details.
Thanks.

Okay guys, we all agree that displacement rules all. However, I think there is such a thing as "horses for courses". For road racing, the engine is always on the boil, and pulling at high revs. An A14 might benefit here, (epecially if the same amount of hp is achieved using a thousand more revs) but for drag racing, an A15 with all out torque wins. Agree?

I totally agree. 5mm is significant. The rod length is same for A15 as A14. The rod to stroke ratio is similar to Ford's 302 engine in the A15. Nobody would consider that to be a non-revver, but the bore to stroke ratio is much smaller in the A15. I would expect that to have a compound effect. Who has got a A15 with dual carbs and big cam and can tell us what it's like to drive?

I am proposing to build an A15 aswell. I'm on the fence with building an A14 though, because they can rev more.
Assuming I were to use a genuine GX head with 44mm carbs, which one would give more power? With one the torque would come at low revs, but the other would rev more and give more top end.
Any comments?
