Taking It To The Track

congrats for your 11 seconds time slips on the first time out. 5 in. of vacuum idling in park aint much, your power valve is probably open all the time. also, from your et, you should be going 115 mph or so , as you already know. i suspect that this 3310 is where you could improve. if you could borrow a double-pumper that is in good shape... look at the vacuum reading with the double pumper, it should go up. if vacuum doesnt improve, try twisting the distributor. that 508 cam will like a lot of initial advance. none of this costs money. have fun! and be ready for personnal bests!
