Are these guesses for first run down the track or best run of the day after tuning? Or ? What gear will it have? What is the rest of the combination that you will have in it when it counts for the contest
I will tune it my best and it's best run will be the counter. That's only fair to the RV :)
RV 440. Stock cam, internals, and block, and wearing the 452 heads. It did have one rusty cylinder, I removed that piston and honed that one cylinder so.....LOL. Here is what I did before installing it in the '79 Magnum:
440 Torker intake on it. I do have the factory cast intake.
452 Heads . I had a valve job done, new springs, and I did touch the casting up some with a dremel but I wouldn't say "ported". I also, to make up the difference in the thick gaskets I used vs factory, cut them .030 so should be same as stock compression (very low..lol).
Installed a new timing chain. I did go 2* advanced when i installed it, but probably back to TDC after running it for a bit here and there. LOL
I'm using the carb off the 5.9. 750 DP.
The Truck - as it sits with the 5.9. Same converter (cheap off the shelf hughes). I may pull the 4.30's for something like 3.23's if it runs out of lungs by the 1/8 mile... lol
