old school tunnel ram set-up tuning

[rat tuned]

i just picked up a weiand oval port street tunnel ram with 2 holley 450 carbs. i have some limited experience with 2 tunnel ram setups that were both positive. the engine is a 10-1 454 with an extreme 274H cam. also have a unilite and msd 6-al that will be installed. heads are lightly ported with 2.19-1.88 valves. t-400 trans with a 10" 3200 converter. also a 12 bolt with 4.88 gears and ET street tires.

i plan to rebuild the carbs to stock specs. car now makes 13" vacuum and plan to install 6.5 power valves. should i jet up 1-2 jet sizes from stock? any other tuning tricks anyone wants to share is great by me. i'm really hoping the small runner and small carbs will keep it somewhat responsive. thanx mike
