WTB - 4” Stroke 3” Main Crank
 
Anyone have one laying around they’re not going to use? I’m thinking of building a 435 out of my .040 400.
PM me
Thanks

Anyone?

Molnar Technologies has forged cranks available for around $1100.00.

ponchjoe 12-12-2024 11:14 PM

I know, not wanting to have to spend $1200. Was hoping someone had a cast version sitting around

I have a never-run Scat 4340 that has been lightened and knife edged.

2.200 BBC rod journal.

3.00 main journal.

4” stroke.

Can post pics and figure a price tomorrow (Monday, 2/6). Located in Illinois (Chicago area).

My original intention was to do the same for my 65- basically make a 3" main 421. cost for a 4.25' is the same if not cheaper.

if cast works go up to a 4.25" stroke. That is what I ended up doing for my 389, but I was buying pistons already. Dished 389 pistons are not a cheap hobby...

Butler has cast eagle in that stroke for what I thought was relatively affordable. Spotts is building my engine he said they are good to 6k rpm.

That’s too easy. I don’t want a 462, I like the revving 428 better

Curiosity got me...How high do you want to rev it? My old stock crank 455 saw 7500 on a regular basis...The 482" turbo engine will see 8000 with a 4.250 crank.

Still looking for a crank

Half-Inch Stud 11-23-2025 08:45 AM

A have a STD STD 421 ArmaSteel. Still holding out for a set of 8 STD 428 piston to fit the 421STD going +030. Also have a set of used TRW 428+040 that check out.

Bob,

I assume you mean a standard 428 crank? (3.25” mains)??

Bob Eiler 11-26-2025 01:05 AM

428 crank
 
Yes

Does this go with the 428 block we talked about last year?

Bob Eiler 11-26-2025 09:13 PM

428 crank
 
Not for $150. I would take $400 for the crank and block.
