Don Terrill’s Speed-Talk

Back in the early 90's did engines and fab work for a Trans Am road race team. The team had left Ohio in late winter to do some tire testing in late winter for Hoosier (they were on a Hoosier deal) in Atlanta GA. When they came back with all these new compound tires they were called and told when un...

The Meta-Lax process: http://www.meta-lax.com/?gclid=CJK9sYKkwJMCFRQYsgodWROVBw is claimed to do the job without the need to run your block around the world 4 times under the hood of a school bus. I had my forty year old ZL1 BBC heads done recently after a ton of seat and porting work, but haven't ...

I have a P&G tester (would like to sell) The instructions I have say to spray a little WD-40 in the tube if it hasn't been used for a while or after testing 10 engines. 1) remove all spark plugs and remove pushrods from cyl.being checked 2)install adaptor that matches plug size and length 3) mak...

You may want to offset the intake lifter bores to help the pushrods clear the intake runners on that short of deck. More than likely you will be in the bottom corner of the port. That was my expierance with the D heads not sure if it would come into play with the C heads. Something else to think abo...

Dave Koehler and Shumarc have defintley been there, as I have also. You can't add more radius than what was there... but we always tried. Also when you would get some Chrysler and Buick cranks that had the rolled fillets from the factory complaining that you didnt put any radius on the crank! OKAY?....

Take a look at your bearing book. The 400 bearings can be line honed to match the 350 main bore and just cut the flanges off the thrust brg. I dont have my brg. book in front of me but if i remember right the .010 400 mains end up at the 350 main bore size. Brent

Dont want to hi jack this thread........But why does RW TECH suggest the second ring should be .010-.012 larger? Doesnt say why. Built quite of few land and sea 540's Never tried the larger 2nd ring end gap. Never any signs of carbon/fuel past the top ring. No sign of butting and below the the top r...

Food for thought, Years ago didnt Champion Spark Plugs in their tech/plug book claim that their plug was better than others due to the technolgy of fragmented spark? Fragmented spark ( I think that was the correct term they used.....Bill Jones might correct me ) The claim was that with enough spark ...

67Jeff, I have a new set of the AFR fully CNC 355 heads out in my shop. I will try to get you some sizes here in the next day or so.
BTW welcome to the forum. Brent

Stevespeed, Yeah I think they are rated for 800# What are the Jesel or T&d rated for? I haved used the Jesels sportsman with a little more open pressure with no probs. He didnt liked the idea of roller bearings cause it might be streeet driven at times....but mostly bracket racing. Less parts th...

Have one that wants it on B/B chevy (sportsman series)
How compariable to Jesel or T&D
Good,bad or just peeing up a rope?

Any of you have had experiance with these?
Thanks, Brent

Orfice? What if you took that and applied it to a balloon? Yes it might expand quicker without a restriction inline. I set my twin Guage at 100 psi and then read the numbers on the other one to get my percentage so I dont have to do the math. Yes I will at times open a valve or disconnect the tester...

hARDCORE is spot on. The intake guides on those heads are surrounded by water and are stepped. The guide OD are smaller on the combustion side than on the spring side. So if you replace the the whole guide .... drive it from the combustion side toward the V/C . You could possibly use liners to step ...

Going low to mid 8's then stepping it upto mid 7's ... I figuire about 20 mph faster in the 1/4. Thats getting after it! When .90 racing and then just bracket race and let it fly i would pick up 10-13 mph....... I could defintley tell the diff, cause my car had no wing per say and it was 102 wb. Plu...

I have put 2bbl carbs on 4 bbl open plenum intakes like that before for round trackers
Customers claimed they could tell a differance in more power. But none was dynoed. Just seat of the pants. Brent
