I made the mistake of thinking the NGK heat ranges weren't backwards, lol...
On the other hand I had some brand new Chanpion R9YC's from who knows what in the garage, so I tried those in between the FR5 and FR4, car ran like total crap!
But I digress...
I ran Autolite 65's with a Holley 750 for a while. My Dad and I played around with the timing, just by ear, and ironically enough, the car ran the best it has ever run that day!
Here is a short video from that day.
Unfortunately, the carb was vacuum leaking at the throttle shaft, so I shelved it. Might just buy a new baseplate and run it....though the Proform and Quickfuel Blaclk Diamond carbs have quite an allure.
Guys, to be honest, I keep coming back to thinking this is carb related.
I pulled the 800cfm Edelbrock back apart, and found that while the float height was correct at 7/16, the drop was only about 3/4, not the 15/16- 1" called for. Sunday when I'm off I'm gonna reinstall the 800 and see what happens.If that goes badly I'll try some other plugs gapped to .035. I have been gapping .045 since that's what MSD calls correct for my box. If that doesn't help I'll cut a new set of Accel Super Stock wires I have laying around.
Is there any reason a Mityvac would be inaccurate for compression testing?
I would like to do a leakdown test, also.
Should I just invest in a real tester?...or just rent one from the parts store?
Also planning to install an AFR meter if If I can spare the cash after some dental bills on Tuesday.
