static and dynamic compression and pump gas
1/8 mile I would run the 4.10 with a 26" tire.
How fast are you thinking that combo might run? Just asking, cuz I don't know.
Ima thinking 85ish. Admittedly a guess.
If 85 and with 4.10s and 26s, that would be ~4730 in direct,~6860 in second.
Ima thinking that Thumpr cam in a 318 is gonna want to trap quite a bit higher than 4730, and a lot less than 6860,lol. And because it is a 318, and a dedicated race car, I would really really want to use up all three gears in that 904.
To go 85 is 108 in the qtr, and that takes a W/P of 9.8; so at 3200pounds race ready will require 327hp or 1.03 hp per cubic inch, which is not a big stretch for this combo. Maybe it will go a lil faster, but I believe 85 is in the ballpark.
IMO the 235/249/107 cam will peak around 5400/5600, so say 5500 and the 107cam is gonna roll over pretty quick, so I see a trap rpm of say 5700/5800. And with a 26" tire,that would take 5.23s, which rounds down to 5.13s
And 5.13s might like that 2800TC, at least for a little while, cuz 5.13x2.45= a starter gear of 12.57, which at 2800rpm should be a reasonable launch, and if not, the 5.13s are gonna kick the Rs up pretty quick.
Those 5.13s are good to 89mph@5900, if I'm wrong. To go 89 is 110 in the qtr, and a W/P of 9.3,so 344 horsepower or 1.08 hp/ cube;meh, probably not with this combo.
Like I said, just guessing.
