I am about to start a build on a 428 stroker.

The story starts with a old worn out c6 transmission in my 69 ford F250. The truck is a long bed camper special with 4.11 gears in the dana 60. I used to drive the old truck like I stole it when I was 18 and finally busted the c6. I parked the truck behind my parents house for the past 12 years while I went to college. (It took me a while okay. Learnin is tough.) About a year ago I had the transmission rebuilt and its good to go. Wrong.

The truck had a rebuilt 360 in it that was running good when I parked it. Well, I tried to start it and it ran but I ended up bending all the pushrods. The bottom end looked good so I was going to just do a top end rework and get it back on the road.

I found a set of C1AE heads at a machine shop that already had oversized valves and had been reworked.

I figured that the bottom end was going to go next. The machine shop owner told me about a .60 over 428 that whad been sitting around for a long time that the guy never paid for. long story short. I paid the guy $160 for his block and the machine shop $340. The shop will have the block ready next week sometime.

A couple of years back I was at a swap meet and found a scat 4.25 that a guy had spun a bearing on. I picked it up cheap because what did I have to loose. The shop is looking into grinding it for me now. I should no more on Monday.

So that's where I'm at. I would be happy to give you guys lots of cool pictures and info. This will be my first rebuild and any advice is appreciated. First, I need to figure out what pistons I need. I would like to keep the Compression ratio as low as I can on this build because the engine is going on a pretty heavy vehicle and I don't want to have to run 110 race fuel.

I was looking at the 4.190 28CC dish ICON pistons in summit with some 6.700 SCAT I beam rods. That should give me around 10:1 compression by my calculations. I feel like I should be closer to the 9.5:1 mark. Any ideas on what I should do?

 

Cool stuff

Let the discussion begin!

 

Sounds like it will be a great tow engine, I'm envious. I can't help you much on piston selection but your on the right track by trying to keep the compression ratio at 9.5 or lower.

 

Have them sonic check the block, .060 is getting pretty thin on a 428. It'll probably be ok as long as you don't rev it to high, I'd limit it to 5500 or less and if you stay under 4500 it should last for years.
Had a friend years ago that raced a .060 over 428 turning over 6000 rpm, he keep cracking cylinders. Another guy got the engine and bored another block for the .060 over pistons sticking it in his Galaxie and drove it for years
