Edelbrock Big Runners ..
The new 355 is going back together next week. The guys at the machine shop convinced me that it's gonna be good to go with Keith Black pistons, won't have the short ringlands the previous hyperteutetic pistons had with low the tension rings, no low tension this time around. The heads are 23º Trick Flow, w/TFS. cam .. 228º/234º. I was talking with Bob Joencke at his shop the other day, he has been designing Edelbrock intakes, probably for 50 years, anyway I can get the Edelbrock big runner's from him for a good price. What can I expect to get in performance terms with the bigger siamesed runners vs. the original TPI w/52 mil. BBk. TB., I'm currently using. The Edelbrock runners look like real quality, and it's probably a good time to make the decision since it's all apart in the machine shop now.

You have to attack the whole system. There was an post here a few weeks ago that linked to a thread at thirdgen.org that talked about a "Super Rod" magazine article on TPI Intakes.
Stock TPI (410hp, 500lb-ft) 47 MM TB
Edelbrock High-Flo (431hp, 501lb-ft) 47 MM TB
Extrude Hone base & ASM LT's (451hp, 534lb-ft) 52 MM TB
TPIS Big Mouth System (460hp, 534lb-ft) 52 MM TB
ASM Siamesed Runners (464hp, 510lb-ft) 52 MM TB
Now these numbers are on a 383, with a huge cam, but notice the increase in TQ and HP buy going to the better base and runners. Even Extrude Honing your stock base would yeild great results. The argument could be made that the 47 MM TB on the edelbrock system chocked some airflow and prevented the engine from making some more power and TQ.
Here is the link to the thirdgen.org thread. Someone posted the entire article so you can read it in the thread.

Go with the TPIS/ArizonaSpeed Marine runners. They flow the best out of the box. Also they are the largest diameter (inside) at 1.660 inches. The Edelbrock are 1.600.
TPIS charges $475....Arizona $399. They are made by Arizona Speed/Marine.
