Cost Differential 468 vs 505?

Post  Dark Horse of Apocalypse on August 12th 2014, 3:06 pm

A 509 can be built from a stock bore(429-460 block) +.060, assuming forged pistons( pump gas friendly 10.7:1 with ported FMS SCJ aluminum heads) rods(6.8 inch) & crank(4.15) would this cost much more than a 468 stock block with forged rods & crank?

With a moderate cam, single plane intake, and a 1050 Holley carb would the above stroker be able to make 600-680 hp & tq at around 5800 or 6200 rpm?

I blew up engine this April and will share what it has cost me. I had a stock stroke .030 over with A429 heads full ported, custom roller cam. I either broke a wrist pin or piston. Rod thru pan, cap through pan rail. Able to save block, cam and heads. I could have built a stroker MUCH cheaper then what it cost me to put this back together. But I didn't want to build a stroker engine with the heads I have so I decided to put it back together with stoke stroke. I had a 429 truck crank offset ground to 3.85 stroke and 2.200 rod journal. $510 I had GRP make me a set of aluminum rods. $1354. I had Diamond make custom pistons, 4.393 bore with a 15 cc dome and .165 wall tool steel pins no rings. $1184. So just for the money I have in rods, pistons and rings I could have bought a stroker. With bearings and rings included. But that wasn't the way I wanted to go. Just sharing my experience.

Melvin,I take it that you already had the steel crank too get off for just $510?

I had one that the shop ground without checking first. Turns out it was cracked. He had the crank and did the work for 510 including the crank. I got off really cheap on that deal.

Lunati sells a 4.16 inch stroker crank for around $700-800. This with a +.060 Overbore would give me a 511.

When I built my 523 it was within $200 dollars to build a stroker vs. a stock stroke deal.

If you can't make 650 with what you outlined something is wrong.

Are you ci limited? If not and you are getting everything anyways, why not go to the forged 4.3 or 4.5 stoke crank and get the bigger motor. Just a thought unless you really want a small ci deal.

I understand a stock block 429-460 will go out to 557 CID but why start there let the engine grow as needed. Bu then move on to build a 511 to start out with then maybe a 557 later.
