Opinion for 525hp small block build

[2Gunz]

Im not any sort of engine expert..... but....

Why not Turbo or supercharge the engine?

It should get better gas mileage, live longer, and be alot better on the street.

And it would prolly be cheaper to build.

The turbo or charger cost is high.

But exotic head work, cam, heads, and tuneups wont come cheap either.

And besides, a crazy turbo setup looks killer!

Challenger340, How are ya doing on that 408 dyno test?  I know you are busy but I would really like to see what you came up with. Kyle

It's all done and ready Kyle, Apologies on the timeframe, I know you're interested, but it's sitting "in line" for the dyno. Probably somewhere around the end of next week I hope.

It's "that time" of year again, up here in "canaduh".

I don't own the dyno, it's a friends who runs an independant testing facility down the road from me, he dyno's for alot of Nascar, Sprint, & drag teams as well.

Usually, we get preference for dyno time, but, this time of year, I have "no time" to even be present or use the dyno ourselves.

We just drop them off, pick them up when he's finished on the dyno. We have 3 sitting there now.

Stay tuned, I'll post the results as soon as I have them, but really, the lower H.P. street deals can get "bumped" from dyno time when "teams" are pressed right now.

In the meantime, I'll get the specs and some photos up tonight on the combo.

Might be kind of fun to "pick it apart" or guess at what it'll do prior to the dyno'ing.

Once again, we changed some stuff up a bit, to see where it goes. New Cam profile being tested again !

Well.......?

[Challenger340]

Apologies for the timeframe, STUPID busy ! Poor little thing got bumped & bumped & bumped, but finally.

Anyway, the results are in, 521 peak horsepower/ 520 ft/lbs Torque.
Final backup & safety tune comes in @ 517 H.P. & 515 Torque ?
We always back 'em down a bit before finishing.

I forget again already !

Will get the sheets scanned and up here shortly. Nice little small block, pump fuel, eddy heads

Again, sorry for the suspense.

The final result as per our dyno testing.

No surprise here for anybody who knows me.

I like TORQUE, especially when it comes to "street type pump gas" engines.

I really don't get to overly concerned with the horsepower thing, for the street stuff, because the rpm required as a function of Horsepower, is usually, the MOST destructive force on the stock blocks, as this one is.

TORQUE is KING on the street, even with smallblocks, especially with our older BIG HEAVY cars

Run it 6,000 rpm, and call it GOOD !
