Re: 427 small block prices (gerry72)
Sure, you can make the torque easier in a big block due to the big heads but with what's available in the aftermarket for smallblock heads, it's pretty easy to support the air flow.

[QUOTE]Cappy did you get your 427 dialed in yet? How about the roll bars?
George,
I have not installed roll bars yet.....and still awaiting time on the dyno. When I'm ready they are not...and when they are ready, I can't get the car in to them.
We are still trying to fine tune the fuel issue.....seems fuel pressure is low at top end so I cranked it up to 8 psi. Started at 5 psi and working up slowly.
Tomorrow I'll do another high speed run to see if she falling off....I should get a fuel pressure gauge that I can see from the drivers seat.

Cappy you can't get Maurice or Norris to sit up on the wiper valance with your hood removed to watch the pressure gauge? :crazy:
I'm surprized that your having feed problems with an electric pump???

Re: 427 small block prices (74droptop)
I looked at all of the above. The Ohio Crank 434 looked interesting until I started to figure out what my compression would be. The smaller head chamber sizes with a large cylinder displacement and the pistons they were using resulted in a CR in the 11's. I decided to go with a local race engine builder who is building me a 427 @ 10.5:1 CR with all top shelf racing parts.. Dart Pro1 200CC heads, roller cam, Dart Little "M" block etc. for about 8000.00. I am also swaping in a TCI Street Fighter Turbo 400 with a 2200 stall converter.

Norris and Maurice..... sounds like a good idea to me.....How do we explain it to the cops??????
No problem with the fuel pump other than I may have it set too low for this engine. :cheers:

Re: 427 small block prices (KJL)
KJL - IMO you need to rethink those small pro1 heads. They would even be marginal on a 383.
My project 427 will also end up right over $8000. That's just less ignition and carb. I am using the better parts

Re: 427 small block prices (gkull)
gkull,
Looking for more low end torque Com Cam recomended XE-282-HR @.050 230/236 .544/.555 w/1.6 rockers. The AFR people recomended 195's!! Comp Cam recomended the Pro1 200's. I agree with you, they seem small.
Are you going dual plan or single?
Thanks!

But you will have the satisfaction "Knowing it runs"

Re: 427 small block prices (KJL)
KJL - IMO stay away from Comp Cams. The biggest problem with them is what they call a small base circle cam really isn't when compared against a Crane small base circle. My last crane cams were .900 & .930 diameter Comp cams were both 1.050 inches in diameter. That's a whole 1/10th of an inch that has to be ground out of your expensive H-Beam 4340 rods.
Double click on my above DD2000 - Then look at the foot pounds of TQ graph - Then explain to me why you want some cam to regain low end TQ? Then also compare your heads against the intake CC and valve size that's run on a typical hot rodded big block. Or better the CFM of are flow
I have not used a dual plane manifold in 14+ years even on my small 350 ci motors. You can't run a smaller manifold port than your head port.
