Anyone do a straight across swap,from ported factory heads,to worked W-2's?
I don't know. I think I'm gonna have to disagree on that one. The 4.10 with 28" tire is really the perfect in between combo for street driving and still getting decent times at the track. It's essentially the same ratio as a 26" tire with 3.73 gears.
Yeah, that's probably true. However, based on calculations I did with regard to tire size, gears and rpm, 4.30 was right on. If it were a race-only car, I probably would have stuck with the 4.30s. This is all on paper though and the 4.10 is in regardless of the math.
I actually built the 4.10 several years prior to getting the Duster. It's one of the aluminum center sections that Mopar was selling about 10 years back. I basically just wanted to put it in for no other reason than I got tired of looking at it on the shelf. I figured it would not make a huge difference and might even help. There is/was a lot of torque multiplication going on in the driveline with the low gear set in the trans and the 4.30 gears. Probably takes a little horsepower to get it going.
Yes true. I was just trying to make a point that I think your car has much more potential than what it is showing. It just sounds like it needs a couple little tweaks and you'll be mid 11's no problem and maybe even low 11's.
Agreed. :thumbup:
Most of the stuff I did to it over the last year was weight reduction and chassis. I gotta figure what was done (a lot -
see here) should be worth a couple tenths, engine and trans being the only things that remained basically the same. Tuning and driving are the last hurdles.
And again, I'm just playing devil's advocate in regards to whether W2s are worth it. They are probably the best of the SBM iron heads so if you think about it that regard, they are worth switching to regardless of financial commitment.
