Fe 410 bored to 428

[mjhcobra]

Sounds like I must be the only test case for this. I got my 410 out of a 67 Mercury. The story I was told was that it was an engine used only by Mercury for the Maurader? and one other boat of a sedan. The nice thing was that it had the correct casting numbers on the block so I rebuilt the entire engine, changed the heads to match the ports on a factory PI intake, put in a CJ cam, and ended up with a nice factory looking setup. I had the assembly balanced and the walls checked and all was found to be ok. This was done in 93 before the internet and alot of the current stroker motors. I recently resumed the construction of my EM kit and hope to have it done by the end of the year. No real time on the engine other than the ocassional startup to keep the fluids running. The stroker is probably the way to go, but I had to have a PI 428 in my car. Good luck with your choice.

Steve, Stoke pistons will be fine, but if anybody can tell me a source
for these parts, great.
mjh, I was told this eng of mine was in 67 Gran Marque ?
I was thinking of a Cam ( Hot street )
I made contact with Kanter Auto Products in N J, but they dont sell
oversize Pistons or non stock cams.
I'm sure all you Knowledgable guys will, steer me in the right direction.
You guys are lucky, don't have to go far for your gear.
Ricky, what would a set of BBC rods cost ?
Cheers - Doc.

Talk to Keith about a Scat stroker crank, a set of BBC rods and a set of entry level forged pistons. I think the 0.20" over bore will dictate who you get them from. By the time you do magnafluxing (see if there's cracks in crank and rods) crank turning, rod prep/resizing you'll be well on your way to spending what you would have with the new stuff. With a stroker crank (4.125 or 4.25 stroke) You can have big cubes without boring the snot out of the block. The Chebby rods have wider bearings with smaller journals, much better suited for stouter rod loads. (HP production)

This is a killer special Keith is offering on his web site, a forged crank too.. You can probably get a scat cast crank package with I-beam rods for 3 or 4 hundred less. Other board vendors can help you too.

If your looking to do a inexpensive street build the 390 "truck" pistons use the same compression height (1.660 in.) as the 410.
Such as Federal Z381 http://store.summitracing.com/partde...0&autoview=sku

390 car uses 1.759 in. height http://store.summitracing.com/partde...0&autoview=sku

I totally agree w/recommendation to talk to Keith. Great guy!!

Since a 410 is 4.05" bore (like the 390), why not go +.030" overbore? There is a bigger selection of 4.08" pistons to go with the stroker cranks. And if you go with a stroker crank, you already have a 3.98 stroke, why mess w/4.125, why not go with the 4.25 and you'll have a 445? A +.030 390 block should be fine; most 390's will take up to a +.060" overbore w/o sonic testing, but I wouldn't go any farther than /060" w/o sonic testing. IMHO.

Keith can fix you up w/stroker crank, I-beam or H-beam 6.700" rods (BBC) and correct pistons, all in one neat package.

I thought the 410 engines used 360 pistons?????????? for the pin height and compression........

360 uses a 1.759 piston height with a longer rod (6.54"), shorter stroke.

you need the shorter pin height 1.660 for the 410/428 crank
