How To Measure Fuel Volume.
I'll try to address all of the ideas that have been posted!
First, I did a compression test (warm, throttle open), but haven't done a leakdown yet.
1) 180
2) 170
3) 185
4) 185
5) 170
6) 180
7) 170
8) 170
The entire drivetrain is out of a totaled Pro Street D150. It's a .030 360 that the seller didn't know much about, so I took it apart. It was all good so I reassembled it with new rings and bearings. It has the 750 vac carb I mentioned. I put the lightest spring in it. (Jetting info below.) Torker II, Unilite w/o vacuum advance, heads are 3418915's that have 2.02's, 1.60's and have been ported. I don't know anything else about them. MP 292* 508 cam, installed at 108 ICL (per Mopar Perf.). Total is 35*. I neglected to check valve spring pressure, but I haven't floated them. Crane gold 1.5 rockers. KB 190 pistons. I don't have the numbers handy, but the static compression worked out to about 11.1:1. I have no idea about dynamic compression. Hooker 1 3/4 (Part no. 5204, I believe?), w/ 2 1/2 H-pipe, Hooker Max Flo mufflers (no drone!), dumps.
It pulls 7" vacuum at 1200, out of gear.
I just checked valve adjustment the other day. They were good. About a half turn past zero.
I just took the line from the carb and put it in a gallon bottle. Turned the pump on and the jug was a bit over 1/2 full in 20 seconds. Seems good there.
The truck I took the drive line from had a 9" Ford rear with 4.10s' that were noisy. Being a Pro Street, it had tall (and wide) tires. Soooo, I put a 26" tire on it and 4.33 gears. Now I have 28" tires, that I haven't tried yet. Sounds like I am over-geared?
I don't record air conditions because it's a toy, but I guess I should. I ran it last summer and last fall. I used to race, and I would call the summer conditions "average". They weren't nasty humid summer days, but it wasn't "mineshaft". Jetting then was 72/76.
When I went in the fall, I used 74/78, but had no basis to do so. Jetting and air didn't affect the feeling of it laying down. Seems it was going 90's in the summer, and 80's in the fall. But I don't have enough good runs on the car to say for sure.
Fuel pressure readings are taken from the carb, where it splits from front to rear. I have a cowl mounted gauge that I can see on the track.
I'd like to try a double pumper. I'll have to make friends with the right person!
I cherry-picked 2 good runs from my fall outing.
