Want to bridgeport my 12a 84, but dont know which intake ports to add the eyebrow to, i already got racing beats template, and took engine apart. I know that they are four intake ports, 1 on the front , 2 in the middle and 1 in the back. I did do a search but it really didnt help me. so any info would help thanx

 

DO ALL OF THEM!!!!

 

Yip, Dj is completely right.Do all of them,you will get the best hp results out of it.What apex seals are you using/planning to use, bearings,oil pressure

 

Thanks for the info. As for the apex seals i already got the carbon race apex seals and springs from racing beat,
and about the bearings and oil pressure dont know yet.

 

Use the bearings you have, get grooves cut if you want but use the bearings you have. Then do the typical stuff for a high rev motor: hardened, lightened, balanced, pinned, etc...
