The intake contacts no water or oil, the SB2 uses a valley tray and with a standard deck height block a normal distributor works fine. On the Dart Iron Eagle and Aluminum blocks, they changed the distributor angle 1˚ that moves the distributor over a little. On a 9.300 deck it requires a slip collar...

Pistons and cam up everything is different. That one also has SB2 lifter bores, but not a requirement.

Not quite that big, how about my 461CI SBC?

If you go the 434 route I would highly suggest using a 2" rod journal. Don't let anyone try to tell you it will be too weak, Pro Stock runs Honda 1.88 rods and 283 mains at 500 inches. Your clearance issues will be minimal with a 2" rod, the large journal has issues not only with the block...

Only ATI.

Not uncommon for a dual plane. What are you using it for, street only , street/strip or strip only? What are the rest of the engine specs, converter/trans...

Not south, but you have Dave Hartman in Mt Dora, I think he dyno's them at Glen Treadwells shop.

The closer you can get to around 200-300 RPM over peak torque on yours the better it will ET. It could even stand more than 4500 with the combo you have, you have to decide how much you want to live with on the street. Using the smallest core to get in the range you want will help with slippage, a 1...

My suggestion would be a tight 9", more like 4500 stall for best ET. Something that locks well after the stall. Why take it on 150 mile trips? Thats a lot of cam and tight LSA to run that far...

Grass is getting long, hurry on down....

No problem. Anytime you have optimized combos, class cars like super stock, comp eliminator... the extra gear does help. And usually those cars have the best suspension setups and race at tracks with better than average track prep. The same with heavy, low powered vehicles. A glide is usually more e...

My point was the actual weight, close to 100 lbs difference will help ET. Rotating weight as well, saves HP loss. And I still think the right converter helps overcome the loss of the extra gear, but it's all relative to the combination it's going into as well. And the aluminum converter does look ni...

Well, actual weight of the trans is a factor, hard to get a 400 as light as a glide. Worth a little ET. Next, the glide helps cars with too much HP for the suspension, it may be a cop out on fixing the suspension but it works. And I think if the car has the proper gear and converter, the converter w...

Another note, if you need more or less installed height you can get + or - .050 keepers to help out.

Manifold vacuum for a vacuum advance on yours. It will give you more when not under a load.
