Well I was told by a few people that they acid ported heads. Material in the right place can change air flow, & there are a few ways to make the runner smaller to remove material. A little can make a big difference, I have wathed people test on on a flow bench that used modeling clay to help a port. Motors & trans in Stock are far from cheap, light wgt internals in the auto transmissions cost. A few hundredths here & there & you go from 10.01 to a 9.97, maybe they play the game different today.
This is a budget LT1 Stocker with a really mild LT1. Stock pistons, rods, cam, etc. Still index's!

Unported heads?
In 97 I was thinking about racing my 82 in stock & called Woodrow about a motor, he told me what they did but those were iron head motors. There are plenty of tricks in those "stock" motors.
He also told me to buy a running car rather than build one, there were some good running carbed cars for sale @ that time because guys were changing to FI.

Woodro gave you some good advice. There are a lot of EFI cars for sale now, many jobs lost. New guys come in and normally run so slow they give up. People didn't used to quit so easily. I raced a full season before I won a single round. Now, if they can't run fast enough right off, many will go bracket race, or something else easier. About the only fast young guys in my div (4) are driving their Dad's, or an uncle's car, or bought a competitive car from somebody. Not many, anymore, want to stock it out like Tim.

[QUOTE=jim1450;12840582]I look on RJ & classracer once in a while, I looked alot last year before I bought my 98 Z/28. A little to expensive for me & I have made a pretty good living last few years, I thought last time I saw a LS car it was like $35k.
$35K? That is a lot cheaper than building one, plus buying more parts to test to try to make it faster. A LOT cheaper. There are guys paying that for just an engine.

Wasn't Al running one of those big overbore engines? Anyone know what I mean? Stock LS1 is just under 3.900 bore, and weren't some stocker cars running 4.0065 bores or something?

I have never a street gear last longer than 3 passes in my cars lol. Pro gears is what I've always ran they take much more abuse.
I would say just keep an eye on those street gears and run em as long as you can.

Acid porting is only about 40 years old. Nothing new there. Jim1450 the game is played different today. It is much more complicated than before. I could write a pretty big book on stocker heads. They do pour them now. I know it very well since they bounced our record at the beginning of last year for very little off of the spec. Last year was the year they said they were only going to pour ports to gather data so we did not check all of our heads. I guess NHRA changed their minds and did not tell us. Factory heads are far from uniform.
"You don't know what you don't know yet"
We have a 12 bolt in a SS car that runs 9.70s all day with a stick. Pro gears only.
