Stock plastic intake on this one. Our headwork, our custom MAF, our tune in the GM ECU, our specs on the cam.
It's easy to make big numbers with these engines, by throwing more cam at it, but the key is a streetable package, which we have.
It has 450 ft lbs at 3000, 500 lbs at 3800, 574.3 at 5500, 517lbs at 7000
676 hp still at 7400. Idles smooth at 920.
Peak hp was 7000 rpm
peak tq at 5500, but the curve is flat as a pancake.
Thanks

Thank you Jeff !!!!!!

I have mixed motion what direction to go.. But mostly i would appreciate super reliable 600+ tru street engine with lots of torque. This could be the one!!!!!!

If I remember correctly the factory redline is 7k gotta love lightweight factory valvetrain components, titanium valves etc......

No, a hydraulic cam.
I have run solid rollers on the street, but I don't like to sell em to a customer.
We ran this engine to 7800 with the hydraulic roller, upgraded springs of course.
Thanks

I'm looking forward to a price list on your different engine combinations.

What cr are you running?

Thanks for the update.

cool, and I agree. A lot of people claim they have a "streetable" combo and then I find they are running solid rollers It's all good until you are the guy that has a lifter puke at 8000 miles and wipe the motor out... and I have dealt with both in the past - a motor wipe at 8000 miles and a gammut of mileage up to another with 20,000 miles with solids which I swore would be impossible, but it got that far before needing to come apart for going too lean on juice, so we replaced them.

Nice job BTW, that is a good combo to make that much HP/cube with a hyd roller....
