another STROKER thread 427 0r 443
I am going to build a stroker w/ a 390 block. I was crusin thru the web, and went to www.dscmotorsport.com. I have the Block but I was looking for a 390 crank, They have a 390 crankshaft offset ground for a chrys. rod that gets 4.05 stroke.
Would that make some power w/ good cast iron heads? A place in Oklahoma City near me has a 390 GT intake for 2 4's for 2 1/2 Bills. This is for a street rod, and bracket racing ? Any experience w/ this combo?

grumpMark, sounds like you're headed in the right direction. What does this combo use for pistons ? The 390 stroker engines (410 merc and clones) make 425 - 450 horses and more than 500 lbsft of torque without any trouble if they can breath. I would run a pair of heads with 2.09/1.65 as a minimum. I'm looking into whether or not even bigger valves are cost effective. But I am certain you will want better than stock 390 size (2.04/1.55?) Don't worry about finding special heads, put the 2.09/1.65 combo in a pair of C8AE-Hs or D2TE-AAs and you will be fine. If you mean the C7ZX manifold for twin 4s, they are great. You get the eyewash of twin carbs but still have dual plane driveablity. If you plan on running Holley carbs they will be somewhat time consuming to set up the floats and idle mixtures and the linkage takes some sorting out. If you can live with a sinlge 4 barrel, the blue thunder intakes are really nice. DF

I called about the intake and it is an S code 390 gt cast iron intake C7AE9425-E w/ single 4BBL. I have the C8AE-H Heads and a 360 block from a 69 truck. I need to buy a crank and rods anyway. Buying a 390 crank, and having it offset ground seems like the cheapest way to go. I figured on boring the block out, and finding the pistons then. I've read threads here about machineing off the top of pistons to obtain close to 0 deck height, I'll haved to get advice on that.
I want it to breath, will the intake,and the heads I have be workable with some extra work on the heads? Plus I found some adjustable rockers, will that help me w/ my Cam choice.

How long are those Chrysler rods, and what would you be using for pistons? I'm building a 410 right now (360/390 block with a 3.98" stroke 428 crank), and the biggest challenge I've had is finding ways to keep the compression ratio down. I'm using the C8AE-H heads that DF recommended to you, and they only have 69 cc of volume. Using standard 390 pistons would have given me a static CR of 11.5:1 (.030 over with a .041 gasket). I'm using shorter, dished pistons to get the CR down to 9.5:1. Unless the Chrysler rods or your pistons are substantially shorter than the 6.488" rods and pistons from a 390/410/428, I'd think you would have even bigger CR issues to deal with, and going with a shorter rod increases rod angularity (never a good thing) and the possibility of clearance problems.
All that said, I've never tried it. Obviously someone else has, or they wouldn't be selling that setup. Ask them about their experience. And then you go try it and tell the rest of us how it goes!

Name: 390 Ford 443" Stroker
Description: Offset Ground to use Chrysler Rod at 4.02" stroke for 427 or 443 CID Stroker
Price: $375.00 / each
This is a paste of the part description. The exact rod isn't mentioned, but I'd haved to find out from them or my machinist.But for the money, that's alot of HP, and CI. That's what so good about the F.E.

I recently bought a .010/.010 1U 428 crank (3.98" stroke) for $200. Besides being about half the price of that offset ground crank, it uses standard and plentiful 390 rods. You'll need to pay $375 for the crank, plus buy special rods, all for only 4 or so addition cubes. Doesn't sound like a real good deal to me. I'd just put in a 428 crank and be done with it.

Karlsd, Autozone sells pistons for a 76 390 for about 100 bucks. These are actually 410 pistons. Don't know what that will give you for C.R. but it should be better.

Thanks, but I already bought a set. They are probably the same thing. They are Sterling 390 truck pistons, which are somewhat shorter than 390 car pistons and have a .097" dish. I paid a little over a hundred bucks for them. My calculated CR is now about 9.5:1, which I think I can live with. Once I get it all together and installed, I'll see how she runs. If absolutely necessary, I can always pull the heads and polish or open up the chambers a little more.

The mopar rods are from a slant 225
They are ~6.7 long, 2.1875 big end bearing
They take CHEV piston-pins
400 chev piston is best if you can bore the block that far
remember:-
In OZ and seeking 427block /428crank

I'm at about 9.5:1 with 69 cc heads and a .041" gasket.
I don't think you can possibly use 6.7" rods and a 4+" stroke in a FE. The deck height of the FE is only 10.17". A stroke of 4.02" (I also saw 4.05" above, so I don't know which it is) with rods of 6.7" would leave you only 1.36" for piston compression, height, and I'm not familiar with any that are that short. Are the chevy pistons really that short? The shortest FE piston I know of is 1.660", which would put it 0.30" ABOVE the deck at the top of the stroke.

I talked to my machinist this morning. He said it would fit, but the chrys. rods won't hold up w/ alot of HP. He said the 428 crank, and 390 rods was the best way to go and cheapest.

[updated:LAST EDITED ON 12-Nov-01 AT 06:13 PM (EST)]400 chev pistons for "long" (5.7/ 6.0?) rods are very short and last time I calc'ed just right for the 6.7 rods( after a minor skim).
10.17 - 6.7 - (4.05/2) = 1.450
The 400 pistons are light but only come plus 30 4.155 1.5XX deck height
I wouldnt be so hard on the mopar rods, they are nice well finished items with a good size bolts. The old slants had a 4.125(?) stroke.

My buddy's dad had a performance manual from dodge. Part of the procedure for breaking in a slant 6 was to drop it into first and make several 6500rpm blasts with it. That's a lot of swingin going on for a 4 1/8" stroke.
