Smallblock intake manifold shootout.

stroked 340 said

First off you should'nt be comparing any single plane intake to the air gap its a dual-plane..Secondly i don't really read much into what magazines say,they're trying to sell their product..as for me i run the Air Gap on my stroker and 360 it flat out works i've got time slips to prove it,and thats all that counts..:-D

i've never seen a drastic improvement in ET with ANY intake swap (other then a T-Ram. those things just flat out haul ***), thats only happens when you upgrade the rest of the components. BUT.. I'll put up the LD340 (nutter 30+ year old design) against the Performer RPM AirGap any day of the week. theres your DP vs DP comparison. so on a modded enigine IMO this is the pecking order for horsepower and torque:

1. Tunnel Rams (mopar M1)/crossrams (edelbrock STR)
2. pure Race Single plains (Edelbrock Victor/ Holly Strip Dominator)
3. LD340/Performer Rpm/Holley Street Dominator
4. street single plains
5. Six Pack
6. street dual plains/stock TQ's

feel free to add others
