Small Block Stroker 630+HP

[MRL Performance]

Here is our latest build. A 360 stroker that made some real good smooth power. The build went like this

360 block 4.060 bore 4.00 stroke
All forged internals
Racetec flat tops
Procomp heads, fully ported
Harland Sharp rockers
PAC springs
MRL Custom roller cam 250's intake 260's exhaust .600+ lift
MRL Pro Plus lifters
Kevko pan
Super victor intake gasket matched plenum blend
Proform 850 carb
MSD Dist(customer had)
B3 Rocker relocate kit- KICK *** btw
11.6 to 1 compression

This one was a real good runner. It made 633HP at 6400rpm. It made 600+HP from 5750-7000rpm! That's where its at Baby!!!

Torque, well it made plenty of that as well. 500+TQ from 4000-6600. Peaked at 564TQ 5000-5200rpm.

I tested a kit on a 440. We had some real bad geometry issues with the rockers, heads, lifters. It would not go over 5300rpm without 425# of open pressure. A bit much. So we decided to give it a shot. Went from a 1.550 dual spring with 490# spring rate to a Beehive spring with a 370# spring rate and it went to 6000rpm without issue. The wipe on the valve tip went down .090" to just over .040". I was sold. Have been using them since. We ran it with the kit and the BIG spring first to see if it helped and all our issues went away, then we swapped out to the small Beehive. Smooth as silk.

Awesome results thanks for sharing.
Couple of questions if you don't mind answering.
1. What do the heads flow?
2. How much better is the Super Victor over a hogged Victor 340 for a build like this?

heads were 310/220. SV is better for these bigger engines and bumps up mid range torque over the Victor.

Nice build Mike. Would be perfect for my 69 Valiant!

Very impresive Mike. What was your timing and carb setup?

 

[MRL Performance]

Timing was 36* total all in at 4200rpm Carb was a Proform 850, Jetting was stock out of the box.

[MRL Performance]

Where's my "Like" button Mike!

Not to side track too far but the B3 kit seems to come with all the relocation bits but no new push rods , does this mean it works with your existing length push rod ? Btw another great build Mike and great find on this B3 kit .
