starting with a 360.
using new rods, a 428 crank, I understand you get a 410 without any boring. (aside from the .30 over cleanup that may be needed).

I understand 410 pistons are hard to find, and the pin is higher to lower compression, otherwise it'll hit the head.
I heard about the occasional 410 pistons being used on a 'low compression' 390 truck engine.
like these:
Keith Black Silvolite 1139
They are low comp pistons
Would these work?

thanks,
Drew

Welcome aboard!
I'm not a Ford guy, but it's my understanding that the 410 is basicly a 390 (not 360) with a 428 crank. if that's correct then no, the 1139 would not work for you.

YMMV,

I need a second opinion as I do not agree with you.
I think I'll call the company to talk to them, and start doing some math (mental measurements).

thanks,
Drew

oky doky.

The 360, of 360.7 cu in (5.9 L) actual displacement, was introduced in 1968 and phased out at the end of the 1976 year run; it was used in the Ford F Series trucks and pickups. It is a destroked 410 with a bore of 4.05 inches (102.87 mm) and the 352's 3.5 inches (88.90 mm) stroke.

-From Wiki

360 and 390 same bore different cranks

ford cranks 353/36 0 3.500
390/427 3.78
410/428 3.98

If I remember correctly

The Silvolite 1139 has a 1.66 compression height and will work with the 6.49 FE rods and a 428 crank. It'll be a stock 410 though - not a performance engine - and those cheap cast pistons are not good for any abuse. Probe sells a forged piston for the application that's worth looking into.

Thanks alot for that second opinion Barry.... I knew my math was right.
I'll check out probe.

Drew check out this guy for parts. www.survivalmotorsports.com I hear he's pretty good.

Yeah, I've seen the Scat kits.... If I were to go that route I think I'd use the 431 kit. It would only require a 30over bore and would still keep the compression ratio round 10 with appropriate heads.

Sadly enough it seems a kit is going to be cheaper than finding parts here and there.

Hello you may also want to check out Mahle forged piston kits/ forged flat tops & moly rings for 410FE... excellent quality.. kits can be had for 500 ish...

I second FFR428...

Thanks alot again guys, gave me something to think on.
I may very well make a simple/cheap build to 410ish specs with the probe pistons.... something I can play with while I save up/build another engine in the shop.

on another note, when is the book due out Barry?

Book is already late according to the publisher. I have about five chapters to go.... Probably around January at this point.
