Its a stroker 340 with production iron heads, intake, and thermoquad that I ported and set up myself. Over 11:1 compression, solid FT cam. Nothing at all done to the exhaust manifolds, 2.5 inch full length pipes with dynomax utraflow mufflers.

If you need a cam or carb for an application like this, PM me.

I don't do alot of pump gas pure street engines but....

Here's a 416 I did for a guy from North Carolina.....

Dyno #'s off the 416..... Pump 92 octane.

This was my old 428 motor....I actually ran this on 87 Octane almost all the time. It's now in Sweden in a moparts member's Barracuda.

Alright I lied, THIS will be last one......my turbo junk. This is old pic with old turbo on it, I hav'nt taken any new pics since I got new Borg Warner on it on New Years day.

It does run on pump gas, but gotta keep boost & timing tamed down to do it. I have mix of 116 & pump in the car now to run 15 PSI with ~24 degrees timing.

I'll never do another NA motor again..... Boost is only way to fly for ridiculous power & yet a motor that is very docile..... this motor will fire right up on a 15 degree day & sit there & idle like a kitten at 850 RPM. My buddy who was there watching was amazed at the idle, so I cranked it down to 750 for him.... LOL But normally I run it at 850-900 idle. It has 11" of vacuum at 850, if I pull idle up to 950 it has ~13". I don't have power brakes, but that would be on verge of being able to operate power brakes, all that with 1200 HP on tap

Fuel mileage should not be too bad just cruising around, carb is a 900 Billet Aerosol & has 76 Jets with Power Valves. AF on the wideband looks good.... I'm definitely sold on the turbo stuff. Next one might be a procharger though just for something different.

3300# 69 Dart, .030 over stock stroke 340 with flat tops, ported Edelbrocks, 237/242 @ .050 Hughes hydraulic cam, Weiand X-Cellerator, Quick Fuel Q-750, 727, 4.30 geared 8 3/4. It has ran 7.24 @ 95.04 with a 1.53 60' on pump 93. I drive it to work several times a month in nice weather. No where near the fastest or the most powerful by any means.

In response to the 472 build up by hughes engines I run a 461 small block pump gas, naturally aspirated engine. It makes 741hp and 638ft in a 68 barracuda that is totally street legal. It has full interior and full exhaust. Best et 9.75 @ 139.88mph, and ran 10.00 in Vegas 2yrs ago at Mopars at the Strip.

Here's the 461 small block engine in my car.
