406 sbc vs 383.

The minimum acceptable clearance is 0.060 - .080-inch between all moving parts and the block. You can check this with a feeler gauge or welding rod of the appropriate thickness. The reason for using a mirror is to make certain the clearance doesn't close where you can't easily see it or measure it. With this 383 SBC stroker application ...That's pretty much what we see with the 383 vs. 406 units. Our pump-gas 383's average approximately 475 HP and our 400's come in around 575. The problem basically with the 400's is coming up with cores. Many of our customers opt for the aftermarket blocks on the 400's. These blocks are also worth some add'l HP. Thanks, Gary in N.Y. P.S.AFR 195cc SBC Enforcer Cylinder heads feature their Permanent Mold "As-Cast" Technology surfaces on the intake runners, exhaust runners and combustion chambers that allows for extremely accurate and repeatable port location/performance. These budget-friendly heads are perfect for your 350 to 400 cu. in. operating below 6,000 rpm.400 + .030 Over Bore w/ 4.00" stroke crank = 434ci. 400 + .060 Over Bore w/ 4.00" stroke crank = 440ci. As you can see, the 427 would be your cheaper alternative but finding a used block that don't need bored is almost impossible. The 440ci is a bit much for street because of the bore size, cooling may be a problem.

This cam might not sound like you want it though.Jun 24, 2006 · 8,745. In my opinion, if someone owns a 350 block that is a good block, and wants to build a better motor then a 350, a 383 dollar for dollar is about equal and will usually out perform a equal 350. however, if starting from sctrach, without a block, a 400 based motor is a much better choice.

I do a review of the AFR Enforcer SBC head.This was one of the (unfortunately) rare times a car rag actually did tests over several manufacturers. They took a garden variety 500 HP 383 SBC and started swapping intakes. The dual planes were tested with a different (smaller) cam than the single planes. For the Edelbrock RPM Air Gap they ran tests with both cams.

Just look at the heads on a big block compared to the small block. 3) if there is any bit of core shift, you WILL grind thru to the water jacket on a 396. 4) more parts options with a 383 (especially pistons). So, the verdict for me was: to go with a fully forged 383 with a good package. Aim for optimum cam and heads.In looking at the BBC thread those LS5 intake and Performer intake all was talking about 5000 to 5500 range. Im more curious as to how the Air Gap vs RPM work on a motor that makes peak power at 5500 to 6000 versus the same motor with a EPS or Performer on it.
