Does anybody know why Luke Bogacki was DQ'd at Brainerd?

Car was classified in the wrong class.

JRyan · 08-14-2009, 07:24 PM

Apparently, Luke claimed the car as a '70 Nova, but claimed the engine as a 396. A .060 over 396 would be about a 402, but in '70, the engine WAS a 402. Things can get sticky there, as the head cc, piston dome, and intake manifold are different. Bad break and a lot of driving for just a little oversight.

A 396 is listed as a 4.093 std bore, a 402 is 4.125 std bore......about an .030 larger bore size not .060 larger, as I recall from my engine shop days.....symantics, I know, but it would definately matter on a Stocker. It's funny to me how many guys run Stock and don't even know what the heck they are driving car and engine wise.......Thats sure not the way it used to be.......

Piston dome is different between a 396 and 402 and I think the ex valve is slightly diff. I Think there are some things that are different if using the 401 alum head. as in combustion chamber vol. Depends on if it is iron or alum. The piston number and dome ht. would be wrong for sure....

JRyan · 08-14-2009, 09:26 PM

You're right Rich. I was thinking (or wasn't) that both would be legal at an about .060 oversize 396 bore size of 4.155, yet because of piston dome, cc's, intake, (and I forgot, exhaust valve size), they cannot be claimed as the other.

Anyway, the apparent rumor has it that the year/engine mix-up was why Luke got tossed. Sad deal.

Also, the 396 intake is a higher version than the 1970 402 (which is quite flat).

Adger Smith · 08-15-2009, 12:31 AM

Yes Jeff. The '70 intake is the pancake type, but the older tall intake can be used and It looks like the new tall 359 GM Perf Parts intake is optional. I just had to look and it looks like there is quite the mix of ex valve sizes. 69/375 iron =1.72, 69 401 Alum = 1.84, 70 402/w401 alum & iron = 1.88. The head CC is all over the place too. Both 69 & 70 w/401 alum are @ 103.3 CC. the 69 iron 396 is @ 104.9 and the 70 iron 402 is @ 106.9. The pistons have a diffrent height. 69/396 is .361 at 40.05 cc,,, 70/402 is .344 at 39.53 cc
So much for using a 396 +.060 claimed as a 402 + .030. The cubic inches would pass, but it looks like you wouldn't make it through the barn with quite a few other parts. Sorry for being so technical tonight, but I just had to know. Sad deal for Luke too.

I'm not saying it's true in this case, but back in the day a lot of the stocker guys I knew of built their own engines, therefore had first hand knowledge of exactly what they had. Stinks that he went all that way for nothing.
