i need some serious help here. my next set of mods are coming soon (cold air induction and drag radials), and hopefully these will push me into the high 12s. i am currently running low 13s with the following enhancements : cat back exhaust, open filter lid with k&n, removed screens on MAF, 160 degree stat, relocated MAT sensor, throttle enhancer, airfoil, AFPR, ported plenum. after the cold air & radials, i believe the next restriction is the stock TPI manifold. i am looking for the best upgrade, and dont want to waste my money on parts that wont provide the most power. i am not planning to change my cam or heads anytime soon mostly due to cost and labor. this is a subject im sure alot of members would like to know about. which combination of runners/manifold would work best on a mildly worked 350? should that combo be ported further or siamesed? thanks for any information

 

Do you want to stay LTR? I really like the LT1 option personally. If you want to stay LTR, I would say the edelbrock base port matched to the AS&M runners. Though's are supposed to be the best. But for cost reasons if I do not go with the LT1, I will go the SLP runners and siamese the stock base to match. Hope this helps!
