Over bore pistons
did you get any flow numbers out of the head?? or pics?? i know your in boost but if its got bigger ports it will take more to fill them...
i just set mine .003 loose for inital startup, but i think mine tightened up about .004 if i remember...
This is not an NHRA Stocker. This may be a revelation to you, but we are not made out of money, and our original intention was to build a car (turbo /6, early A body) out of
junkyard parts, not buying anything new, for
UNDER $2500.00.
We failed miserably, of course, but Ryan and Tom's cars were so DANGED appealing, that we decided to try to follow their lead, and at least, give the thing a chance, with the K-1 rods and the Wiseco piston/ring setup.
Buying a new tranny, converter, 8.75" rear, Cal Tracs, a roll bar, tubular front suspension, wheels and tires ($400.00 worth of slicks,) a $1,000.00 homebrew header, disc brakes for the front, and the fuel and ignition systems pretty much broke the bank for 2011.
We'd LOVE to send this head to Mike Jeffries for some meaningful flow bench analysis, and see how much he could improve it, but to tell you the truth, a new ball bearing turbo would probably do more for it than whatever improvements he could implement, and probably would cost about the same. Our turbo, though new, isn't the last word...
If we were rich, we'd do both! :)
So, no, we just took our machinist's word on the porting job on that head (he builds lots of race engines,) and will run it as is and hope for the best. If it's NOT
"fast," we'll just crank up the boost... LOL!
That's what I love about bracket racing; no pressure to perform at any particular level... just pressure on yourself.:-?
