How Would You Build This Stroker?

I was in your same shoes a few years ago. I built a 416 4" stroke motor. I ran into a very good deal on a 340 block. But would be fine with a 360. If I were you, just go 360 block.

I think $10K is more than necessary. If you've got that money work with Brian at IMM Engines. He isn't too far from you and he's realistic, practical, helpful, and honest.

I'd look at something between around a 450 HP 4" stroker motor. Easy to fart around in, easy to keep in tune, will light up rear tires at will travelling under 30 mph.

360 std bore basic block -$150-200 used
arp main studs -$ 100.50 for windage tray
4" scat cast crank internally balanced (forged pistons, I beam rods, cast crank) -$1,437.97 Summit
hydraulic cam and lifters: around 235 +/-5 duration @.050 under .525" lift ~$ 230-250
comp iron roller rockers, or durable aluminum rockers $560.97 Summit
smith bros pushrods: around $120
edelbrock aluminum heads or equivalent. maybe pocket ported. Don't really need more head for this HP. W-2's take expensive budget robbing rocker gear. $1600 Summit
melling stock volume oil pump $ 46.97 Summit
head studs $128.78 Summit
air gap intake $ 289.97 Summit
750 vacuum secondary carb $ 292.76 Summit
msd distributor $330 Summit
milodon road race pan $427.95 Summit
milodon oil pick up tube $53.97 Summit
tti step headers or dougs $630 plus

With 20.5cc dish ICON forged pistons and a 63cc advertised head (64cc measured) I have 9.7:1 compression. It doesn't ping on California 91 octane. But it is very close. I can't bump the timing at all.

There's items not listed and I missed. But that gives you a rough idea of parts costs. And gives you ideas of where to save money with good used parts. I just looked them up at Summit cause it was handy. Might be able to beat prices.

People advertise motors like that at 500-475 HP range. So you can call it that much if you wish. I like to under promise/hope for and over deliver/get.

This is very close to my motor except I used a 340 block, solid lifter cam, double pumper over 750 carb, single plane intake. That motor would be a tougher to maintain and tune than the one above. But would be very close in power.
