If someone wants to build a 302 I have a '68 3923279 crank with the rod journals turned down .100 for a small journal rod.

I have been told it was worth about 8 to 10 H.P. to do that to the crank.

That is why the 305's run so good.

Strange how in STOCK, things are really regulated like only offset grinding crank .015", yet you can cut apart a set of heads, move everything and re-weld them back, and tech does/says nothing? aybe that's true, never really been into STOCK. The multi-clutch PG sounds good for the hi-Hp big inch guys, but these smaller motor guys that I know, run 3 speeds, mostly PRO-FLITES. Buddies small tire (29.5 X 10.5 tire), 2780 lbs 440" SB N/A for has also been 1.1025 60's. Again 3 speed PF trans. PG was just off a bit and car would 60 with the 2 speeds and low Hp 440 SB. Now I'm NOT saying you CAN'T get a OEM style lil SB to run mid 11's, just there's something that's not being told??? I can't figure, why this STOCK ELIMINATOR, either K/SA, L/SA or M/SA car, that can legally run mid 11's, why doesn't it hold a record in the class??? Record for K is 11.76, L is 11.82 and m is ONLY 12.35 MINIMUM? MacNeish is listed for D/S though. Trust me, I'm all about going faster then you should with what you have, these are some good examples too. NO DOUBT either way, the car works and the guy is successful in my book..

Current NHRA racing is run on a qualifying set-up in an eliminator bracket. Whoever runs the farthest under the unrealistic standard that is set for each class is the number one qualifier. If by chance, by accident or on purpose, a car and driver was to set a record at the level that they can really run, they would have to qualify against that new record. It's too easy to just leave the records alone and qualify 1 or 1.5 or 2 seconds under the minimum. You can then pick your own dial in and use that number for the rest of the event. Can you say " big bracket race?".

In Stock Class, heads are stock, with stock valve sizes in their stock locations and unported. You can have a 3 angle valve job using any angles.

Buy a class engine that runs on or under the record and pull it apart......have untouched "stock" components on hand for comparison. That's if you can find someone to sell you (an outsider) an engine.
Protest and tear down rules still apply.........And you will NEVER SEE a fellow Class Racer called to Tech for A teardown protest.........NHRA will do a C.I. & a Compression ratio check on occasions. They are at "Risk" themselves...... .....for a "counter protest" Its Racing......if you ain't cheat'n, you ain't race'n.....
