It doesn’t take a really big carb to run better than he is now. I ran 9.80’s with a 750 Holley on my W2 headed 408 shifted at 6400-6600 rpm.
asking about the springs....as the lower price version spring presure at 120 seat pressure.....
I'm also not sure why you're not in the 118-120 mph range.. I would think it would like four or five more degrees of initial timing... I've got to say the carb isn't in big enough as well...
i could be wrong but i doubt with that Howards solid it would be happy at 6500 like he says it is with a 120 spring
I was looking at the compression you posted. What cc are the trick flows? Stock they are 60 cc which I think would put your compression at 10.4:1 with icon ic745 dished pistons which are 20.5 CC’s. But that has nothing to do with your 1/4 mile runs. What fuel system are you running? Are you getting enough fuel on the big end? Fuel pump?
I shimmed mine to a installed height of 1.80 to get them to 140ish....PRH said they were Pac 1903 springs....same spring i use on the eddy and Sm heads with flat tappet cams.....just wanted to point that out
You asked for opinions. Here is mine.
If its gonna just be a street car, leave it alone. As others have suggested, play with the carb a little more.
If, however, you want it to run perform much better, the convertor and carb would be two places to attack the ET that would really wake it up. Not in love with the M1 either, if you are gonna keep it on the street it likely would run better with an airgap, as far as seat of the pants
You have a relatively “ big “ intake on it, “big “ headers on it, but a convertor that doesn't match.
I would bet that a good 4800-5000 flash 8 inch convertor and a 950-1000 cfm race 4150 carb would really wake it up. Cam seems a decent choice, i run the next one up Howards sells( 260/264) in my 360 but its soon going in a 418 where it belongs. Good choice you have made, imo.
Its never going to run where it could until you get it to 60 foot. It should be 1.50 ish. The carb and convertor would, i bet, get it there.
I would also throw the snubber in the garbage can.
Your combo has excellent potential. Could run in the 10’s very easily with modest changes.
Get it to come out of the gate, other incrementals will come around and it will pick up rpm on the big end. Gear and tire are fine. Convertor, carb, convertor, carb
What version of the TF heads did you buy?
That build is damn close spec wise to mine. Except my Howard's cam is a solid roller, but really close spec wise.
And I'm running a 904 with manual valve body. 4500 converter from dynamic.
So far, this combo has given 11.3s @119.55 at 7,000+DA.
I would venture to say a proper converter would wake that sucker up quite a bit.
Edit..
It probably wouldn't hurt to get more seat time and do some tuning before any hard parts get changed. Find out where it's really happy to shift. Start low and work up.
Mess with suspension, simple tweaks can add up.
yep fallon, I live in fernley so it's not too bad a drive.
I don't know about changing the fuel line or the pump if you don't see a lean spike?
I would like to see more passes with a little carb tuning before any more money spending..
