360 engine build opinions - first engine build

needsaresto said

Just for kicks I did a little digging in my magazine library. Mopar muscle did a build over 4 issues back in 2000. 280H cam, smog heads ported out, stock bottom end with fed mogul 116 hyper pistons for 10:1.Torker II single pane?! intake,prolly looking to boost h.p #'s with it.Made over 400lb's of torque and 395 h.p

Also found a build with a stock 360 and stock magnums which made over 400 h.p .Again a bigger cam.

So yes I have to agree 400 h.p is easy, but fuel mileage would drop.

With the price of gas being so stupid, I think it's time to switch to an electric motor and load the trunk with batteries.

Sounds like more porting, single plane, bigger cam. I'd expect more power out of that than the one that we did.

If those were dyno'd at westech, that may be where the increase came from. I've seen an engine that made ~450 on westtech's pump, make 415 on another. I bet that 360 build that was done for my friend would dyno in the 370-380 range at WT. Unfortunately, dynos are a lot like flow benchs, no two are exactly alike.

To add, the dyno that was lower on power, has been closer, as in, almost spot on to the MPH/weight calculators for multiple engines. It was also very close to the camquest and DD numbers, too. I'll believe the numbers of the "conservative" dyno. Dyno numbers are sometimes like having to listen to two guys brag about their johnson. Bigger is better and yours ain't big enough. :)

Moper and needsaresto are right too... keep it simple, 107's, xe268H. Hard combo to beat for a street car. If you chase HP, your doing yourself a disservice. Build for intended use.
