Super Stock Question, 327

trmnatr · 10-31-2008, 11:07 AM

Pretty long here, I got Questions about the CURRENT Super Stock 327 engines rules

-I know the crank stroke cant exceed 3.263"
-I know you can use the GM or Bow Tie block, Due to cost im using an 010 with probally Milodon caps {maybe splayed but probally not being its a wide register block, probally just use Milodon caps that use the factory 4 bolt holes}
-Im using Manley Super Stock legal rods

You used to be able to use a light weight piston {Super Stock} of the same top design, or if it was a dome it had to be no more dome volume than stock but could be lighter -- Is this still the case?

You used to be able to use .031" Dykes top rings, Is this still the case?

The engine will be a 327 10:1, the heads are -291's @ 57.5cc's. Is it still fine to use an .875" wrist pin?

Also, Instead of using the 1.625" H-11 or Manley NexTek 1.64" valve springs, has anybody switched to the PAC1226 which has the same pressure as those two springs but is a 1.55" O.D

Im under the impression they lifted the rules allowing you to run any powerglide, TH400, TH350. Is this the case?

I could not find any information on this on the NHRA site or IHRA - Not sure what we will run in but it will be most likely IHRA which operates off NHRA as a director told me

Do they have any restrictions on oil pans in Super Stock? Also, 10 years ago we would have filled the block with Hardblok, Is the rest of the class using 010 blocks and such doing so?

Also, Timing chain or belt drive?

Any rules on Electric water pumps?

Are Lift bars with adjustable uppers legal as of NOW in Super Stock?

What class would this engine be in if used in a 3750 race weight car in GT, GT/H????? What would be the index in the class this car would fall under?

Thanks for the help !
