Yeah its very impressive, Slawko is doing the heads, valvetrane looks excellent, im excited to see it finished!

There is only a couple really good head guys up here in the PNW that i know and the one that mentored me doesn't use pipemax, i use to have it although i personally never got around to doing any testing with its recommendations

How much gain do you want to see from this combination? What would be considered successful? I'm just curious, it looks like there is a fair amount left on the table

Yes, had that happen when they sent me cam bearings for the wrong block type, there is like 3-4 different cam bearing sets used over the years, if you have an early block the later ones will not go in without a lot of force

An old trick i use is putting feeler gauges in between the rods before torquing them, only on non doweled rods, i also install both rods on a journal before torquing jmo

I see, i wasn't looking at one of the key aspects close enough, sorry for the high Jack

I guess i just don't understand this 128 deal, yeah i understand the math and i have read about it but LSA is just the measurement of distance between intake and exhaust lobe center lines. You can have the same LSA on a bunch different camshafts and have different valve events for every one of them....

Interesting, i haven't seen anything about that

I have a set of Probe FPS forged pistons in a 388 street/strip engine i built 8 years ago and it has the 5/64-5/64-3/16 ring package, you had to spend another couple hundred dollars for forged pistons with skinnier ring grooves at the time atleast for shelf pistons. This engine made 504hp at 57-5900...

So far if anyone else wanted to know what size the box stock port size is i measured them today, all of the ports were pretty consistent With a port height of 1.97-2.00" and a port width of 1.22-1.25" Only issue i have so far is that with edelbrock rpm heads the top of the intake runners s...

Callies use to have a 5140 forged crank 4.00 stroke at around 500-550$ fwiw i use to have one

That's one of those factory racing parts like cross ram intakes and 292 turbo heads that were pretty awesome back in the 70's and it makes for a cool conversation piece or if you were trying to build a vintage race motor using factory parts i can see why you would use it but man you could probably t...

Here is what i did to rebuild a 5.3 before i sold my 06 Silverado 4x4 rcsb Previously it had a solid roller NA 383 LS i built making 467rwhp So this was very mild for me but maybe more than you are thinking 03 block, bored to 3.812 Stock crank,rods with arp bolts, Flat top pistons 10.75:1 compressio...

Thats about a .001" difference, id personally run it

I had a customer accidentally buy solid core wires for a 470 Pontiac i built and my dyno operator almost started buying new parts for the dyno until we figured out what was going on lol
Ive never had an issue with spiral core wires on the dyno i mainly use.
