how much compression do you have?

Not in your sig,but do you have any port work?l live in town and before my port work just domes 21 were fine on pump 91.On 20's I don't know.

you'll probably be pushing it wit stock port timings @ sea level. what's your elevatoin? what was the compression after the build?

i got port work done by trinity ... they did stage 3...

it says its good for ..

Stage III (TT, Aggressive Play,Hill Racing, Drag)

- Mid-range power emphasis

and as for compression .. i would have to chck it but would i be able to do a comp test with a single carb if so how..

thanks..

single carb doesn't change compression. wot, and kick 'till it stops moving
