High horsepower small block

[Ck[FIN]]

I though that i would share my engine with my fellow american friends.    Actually i bought it from my friend who raced many years ago. He built this engine 9 years ago. (Last race 2001). So really, this is "old school" engine. After that it has only been freshened with new bearings and gapless rings and new set of custom made roller rockers. I just had to check it and buy few new parts.













Few specs:
15:1 comp ratio
x-block filled with "concrete"
mopar steel crankshaft with chevy bearings, custom stroke.
BME pistons 4.10
BME aluminium rods
Crane Cams roller 328/336, 0.707/0.693 camshaft
Heads heavily ported and modified by a swedish guy 15years ago. w2, flow approx.330cfm/28"
titanium 2.10 intake valve and 1.67 exh.valve
Intake manifold made by the same swedish guy.
JIR-adjustable timing belt drive system, designed and made by my friend 15years ago. (I think no one had timing belt system for sbm 15 years ago?)
oil pump driven by a belt
JIR-roller rockers, designed (copied from harland sharp and jesel) by my friend, 1.7ratio.
msd 7al, crank trigger
2x750cfm holley dominator, no power valves.

Sorry i dont have dyno sheets because it was dynoed about 9 years ago. They told me it made 750hp/575ft-lbs and huge power at 5500-8500rpm. I can believe it.
Hope you enjoy.

I am planning to put it to my 65 valiant. My last engine was 360 with a blower and it ran 10.66s 1/4mile. Lets see how fast it goes when i get it under the hood in 2 months. What cam do you prefer?

My dad just finished building a big hp sb.  Its a 73 340 punched out to a 416 or 419 i think.  Indy heads, pump gas motor.  N/A it dynoed 630 on the engine dyno.  The engine is in a 73 Challenger w/727 3.23 Dana 60.  On a dynojet it did 515 at the wheels.  We are taking the car to Pinks All Out in Charlotte next month.  Should be lots of fun.

I tried the engine for the first time last weekend. It runs very well and runs pretty strong. I had problems with my msd rev limiter because it only gave me 7500rpm. Engine is used to have 9000rpm on the finish line. Also i had problems with my carbs at the starting line (crappy 1.75s/60ft).

Best run was 10.61s/133mph. I am still happy for the results because car worked very nice with new transmission (txh for the tips tactransman),driveshaft,new gears and new tires.
We will see how it runs in my next race in 3 weeks when i fix those problems.

That is way too cool.  Love the small block with big power. 

[Oldschool]

That's a sweet combo!       You should run solid 9's when you get it sorted out.       What does the car weigh?

I hope for the high 9s this summer. Car is about 2860lbs with driver
