Title: EMC hp guess version 3
Post by: CaptCobrajet on September 26, 2019, 02:06:16 PM: Mine is .575 lift also, after lash. Same rules as Joe and Barry. Mine is a .046 overbore 390, 3.79 stroke, and I used C4AE-G heads. Works out to right at 400 cubes. (mbrunson you can't guess in this game!)

575, same as the cam lift.

I was going to guess the same, maybe even 580, but, even though I've attended the EMC event a few times, I don't know how much the "average HP/TQ" rule will affect his peak numbers in competition trim. I'm still going to guess 565 peak HP, just because. If it wasn't an "average" competition, I'd be guessing 580+....with OEM iron.

Same guess...545 HP / 530 TQ

Post by: mike7570 on September 27, 2019, 07:37:02 PM: I have some interest in this one since it is similar to a stock eliminator build except with more lift, larger valves, porting and a larger carb.
Since I know Blair can build a 1.00sec under (or better) 390 I looked up the F/SA and E/SA index at 1.00sec under and using a Wallace calculator at a 67 Fairlane weight a run that fast would require about 547 flywheel HP +-. So if I add for the porting and cam lift +30hp, a little larger valve +15hp, and larger carb +10hp my wild ass guess is 602hp.

By the way are we guessing peak or average? 602hp is peak.

I thought about it some more and I think CJShaker is right regarding moving the peak down to pick up a better average over the 3000 rpm range for scoring. So with the peak moved down I’m revising my number -20 to 582hp.

Post by: CaptCobrajet on October 13, 2019, 10:21:17 AM: Hey Tom, I think that may be Fake News! Mr. Mike did have the close number..........I think the best I can do is give him a bit of a discount on a project we are involved in. ;D

Sorry guys I couldn’t figure out how to delete the empty post above.

I wanted to say I would take that 390 , but I don’t think it would pass tech!
i’m Working on a 428 stock eliminator build and Blair is supplying me with parts and lots of invaluable advice.
