**69 Post Sedan** · #1 08-10-2010, 06:13 AM

We got the motor on the dyno. With the set up that I have, let's just say, the motor ran very well. Thanks to everyone and your input. It helped me out a lot. [img]<<GRAEMLIN_URL>>/headbang.gif[/img]

I do "hope" to have it in the car and running tomorrow but....we'll see.

I can't wait to drive the car with this motor! [img]<<GRAEMLIN_URL>>/

What are the specs on the motor (bore & stroke, cubic inches etc...)? What kind of power and torque did it put out?

**69 Post Sedan** · #4 08-10-2010, 05:07 PM

The bore is 4.165 and stroke is 3.76 = 410ci. 10.48:1 comp. with 077 aluminum heads.

The dyno numbers came out at came out at 421@6200 and torque was 398@4800.

Nice Street Motor and easy on parts.

Well, I hate to be the fly in the ointment, but those figures seem a bit low to me. To be frank, you've gotta be thinking the same thing after spending a pretty good chunk of change on some nice, premium parts. I've been watching your build and I liked your cylinder head, solid Roller camshaft, and intake choice. I've had similar solid roller BBC's that have made good power and I expected about 460-480 HP out of your motor. What do you think is holding it back from it's potential?

It's in and I actually drove it to the gas station.

I would have figured more also, but as long as it's reliable. We built a 427 about 15 years ago using stock 3/8ths rods, factory comp 11-1 TRW pistons with BONE STOCK 840 heads and a roller cam. The son of gun put out just over 550 HP at 7000 using an Edelbrock victor manifold and a 1050 dominator. Our car weighed just at 3000 lbs and ran low 10.20's at 130 mph. Love the 427's. I have the 077's on my 427 (430hp) superstock motor, which are good heads if done correctly. That motor put out 772 with a very mild porting job per NHRA Volume specs. The 401 heads are the way to go, so if anyone wants a set of 077 heads complete you know where to find me. I want the 401 heads... Brian Oakes and few others are making 850-900 plus HP with their 427's, but are running the 401 GM head
