The 416 xe274h went 12.8 @109 with 3.55 gears and 255/60 ET Streets. Hopefully it will go faster with a better launch. The tires were on rims that were too narrow and not working the best possible. This year, I'm going from 7"rims to 8", putting the original 3.91 back in and changing the Eddy 750 to a Holley 750dp.

The 340/ex268 was much closer to stock, including exhaust manifolds. With 245/60-14 street radials and the 3.55 gears it was going 14.5 @just about or under 100.

The ex274 setup is noticeably more lumpy but still very good at low rpms. I'm suppose a lot of that has to do with the longer stroke. The car has no power anything so vacuum is not really a consideration.

418 STROkER 10.2 comp, eddy heads, comp XE275XL, air gap with an edelbrock 750, TTI headers, right now I fighting with getting the timing/advance dialed in . It is definately a very angry engine with TONS of power and a very aggressive lope when I can get it to idle correctly.

Thank you both very much for posting your combos. Those seem very close to each other for comparing those two cams. Out of those two, I think the XE274H is more for me and the 408 stroker I'm envisioning. I have a vehicle for work, but other than that my Barracuda is my transportation. So it does get driven a lot. I'm going to go to the grocery store right now in it at 10:30pm.

684mulas, what compression are you running? Can you run crappy 91 octane gas in it.

684mulas and 418 STROkER what stoker kits or parts did you choose; what brand crank, rods, pistons?

Did you run the E-brock heads out of the box?
