Wow Mike, I've really enjoyed following your build. I feel it's the spirit of what Jr. Stock is all about. A true do-it-yourself dime rocket.

And you're right about Chip (the Legend) Johnson. Great guy.

Keep chipping (no pun intended) away at it and keep us posted. I see you've got quite a following of true racers that build with their heads, not their wallets.

Good luck.

The powers that are not checking booster size for now. All they worry about is main body venturi size and throttle plate bore size.

Update - Found a set of 1.5 primary tube headers so installed them with 18 inches of 2.5 collector. Changed the converter to one with more stall and about 500 more flash. Leaned the carb up just a bit - from 69 jet down to 66 jets.
The result (in great air 30.4 barometer 495 adj alt) was best runs to date at legal weight (3470) - 9.152 and a 9.156, 73.0 and 72.99 mph in the eighth. Need to get this out to a test and tune since was doing this on race day, looks like on the right track. Car was running consistent 9.39 / 9.40 before at 70.2's mph.

Update - Spent a day last weekend doing test and tune to try and get jetting/timing set, and get some 1/4 mile times.. Best was 14.87 at 1700 D/A. Most were 14.92-14.94. Best was with .064 jet and 40 timing.


So readjusted the valves based on some ideas from this site, for racing this weekend, and HOORAY went 14.84 - UNDER NHRA 1/4 index for the first time. Two other runs 14.91 (changed shift points) and 14.90 first round elims(dialed to high-opponent had way better lite and I dialed a little to high-broke out). The track had issues with the MPH clocks so no 1/4 MPH data for any runs.
I also put on new front tires-same size-and consensus was less rolling resistance since riding on the new tire 'nubbies'-LOL.

Very cool!

Re: 75 Nova U/SA
 

update- November 11 2015 at Virginia Motorsports Park. Three runs in the 14.7's in 1/4, at last under NHRA index. Incredible air, like 95 adjusted altitude. Best of 14.700 at 87.67.

Been accumulating some parts for a 350 2bbl motor, finally have everything (used of course) so going to try my hand a building an engine. Haven't done that in years, just want to give it a go. Going thru all that I have, cleaning parts, picking out the best. Hope to have it in and tested by Charlotte LODRS.

Re: 75 Nova U/SA
 

Did you consider a '76 305 2-bbl?

Re: 75 Nova U/SA
 

Speaking of which, Mike please call me at 513-836-3648. Bob Michael. Leave message with your number if I don't pickup. Thanks.

Re: 75 Nova U/SA
 

I did, and it looks pretty good. But I came across a bunch of very decent 350 pieces/parts for reasonable cost, plus I had a lot of stuff laying around. So won't have more than 2-2.5K in it, and it should be a decent piece. And I can just change the manifold and carb (and year) to a 4bbl and run another 4 classes (automatic) or so. Hey, just having some fun, haven't built an engine in 40 years!
