deckofficer Hydraulic roller. I meant when at car shows with the engine not running you always here spectators comment to each other "Must be a Pinto 2.3 L 4 banger". When the engine is running the cat is out of the bag.

I only took it up to 125 on yesterday's short test drive.

vinniekq2 You would have to be deaf to think that is a 4 banger,lol.Did you get the hydraulic cam or solid option?How does that car at 175 mph?

At that my friend is why I cover things up. First, the Asian Tuner set has no idea I'm lighter than them, and with my narrow engine cover and exhaust tucked up underneath my ride, they assume I'm a 4 cylinder too. Notice the bulge in the side cover for clearance of the Ram's Horn exhaust.

that little red car? Im guessing taction is a problem.should run low 11z
The lighter the car, the less tire spin and more hook and book. Ran Sacramento Raceway with the 355 which had 386 HP, 10.8 @ 132. I would say the 526 HP 427 would be at least a second faster. Weight makes such a big difference for going fast, cornering, and stopping. For over 40 years I had hot rods in the 3500~4200 lb range and now I've decided not to fight The Laws of Physics, going with 1790 lbs. Had I done this 40 years ago, their would have been a lot less hot rods in my garage over the years.

Try light weight, you'll like it. Carroll Shelby had it right.

One of my heavyweights about 25 years ago, and before my beard turned gray.

Though I'm in California, that was why I bought from Scott too. Many stories of his race engines going season after season untouched. That is uncommon for the flogging a race engine receives. I figure if his race engines are that tough, then his street engines ought to be pretty good too. Plus he is able to produce big HP at just 5700 and gobs of torque at 4400. I only have those 40 miles of experience, but in my light weight ride it scoots.

I run the Tremec TKO 600 also, with the 0.64 OD 5th.

Well I've joined you as of today. I really like good off idle performance but missed the high rpm zing of a conventional high performance build. Today drove the Track-T for about 40 miles with its new engine, a Dart block sbc 427. Dyno's at 526 HP @ 5700 and 556 lb/ft @ 4400. Because the intake is taller I will have to massage the hood to get it back on.

vinniekq2 I bought a brand new TKO 600. I ordered the .82 over drive. If you drag race,you might want the .68 overdrive depending on the rear axle ratio you use.The TKO/scattershield/shifter came to 3k. I also bought a lighter sfi approved steel flywheel.I use a diaphragm style clutch.

-350 block, bored .40 over.
-SCAT 375 aftermarket crank. Made for a stroker.
-Keith Black Claimer flat top pistons .40 over with 2 valve relief.
-procomp motorsports 6" connecting rods, I beam
-Lunati roller Cam and lifters. 242 duration, dont have all the specs on me right now..
-Dart SHP Aluminum 200cc Heads - Hand built with large springs, 10 deg hardware including 7/16" arp studs and guide plates as well as performance valves runs, Ferrea Stainless performance valves
-Holley DP 650
-RPM Performer air gap intake manifold.
-Long tube headers, 1 3/4 I believe.

Can anyone estimate a HP range. After all this i wont have alot of cash to dyno it. But an estimation would be nice.


Thanks,
MIke
For what it's worth, technically that would be a 385ci, not 383.

That cam you picked sounds like a 57-6,000 RPM cam,depending on ICL and LDA?

I like the video....Sounds really good...
I was kidding about the sarcasm. But i guess your probably right about the air movement. The heads that I am getting also offer a port job for a couple extra dollars. So it would make sense to get a bigger carb...
What type of 5 speed are you using? I am looking for options and best case scenario. The car is a 72 chevelle...
Thanks,
