Also--I use a crank shop near me in Quebec for my balancing needs and from time to time I get them to grind or in some cases index/offset grind certain cranks (He is so much better than me at it) and for what he charges to offset grind isn't a quarter of the cost of a good new crank. I'm not...

I can't speak for the OP but in my case... I did it because I have a crank grinder and I had a 383/400 steel crank on hand and I wanted to build something unique for my buddy and I've always hated the stupid 3.375" stroke and I made the stroke to fit the piston and rod selection and I like the...

There is no factory hardening, unlike most diesel cranks. Have offset ground many cranks , never an issue. The 3.915" stroke 471 combo was being done in the 80's that I know of and maybe 70's. J.Rob

Watters Dyno Service is the same place that Golds Garage tests at. Nice setup. J.Rob

Yeah, Pretty sure Terry is a Chinadian trying to survive here in the province of Onterrible. J.Rob

Absolutely agree--Its the testing methodology and S.O.P. that could undermine the results. J.Rob

That's the long way, did it that way about 5 times in 1995 and said to myself "There has to be a better way" --Get yourself some 12" vernier calipers and this can be done in about 5 minutes. Accurate to within .001". J.Rob

.012" makes a measurable and noticeable difference-I'd say you were missing out. J.R.

Bombastic as usual YR, This isn't about settling some internet debate once and for all. I think this is interesting and look forward to it--nothing more, nothing less. I just hope the dyno shop has a solid testing methodology and well maintained equipment. J.R.

I'm willing to bet you'll be here when the results are in and this thread that you started is 14 pages deep. Why wouldn't you want to maybe take a little info away from it if you could? J.Rob

Decking an LA is an absolute must. It is more important than a line hone (if youre not dealing with a spun bearing). Ma Mopar left the decks so absurdly tall and random and crooked it is a machining travesty. Skip the line hone and deck it to zero with these Mahle pistons/rings... These are the...

This is at BDC. J.Rob

My buddys carbs are just incredible. J.Rob

I figured I had a T-10 pattern on my plate but I did not. J.Rob

The only shot of the piston I have on my phone. J.Rob

Truing up the exhaust side of the heads. J.Rob

Even monkeyed with an LS style rocker but the customer wanted full roller. J.Rob

I should have milled a slot to capture the pedestal perfectly ticked at myself for thinking of it after the fact. J.Rob

Sorry for the sideways conversion. J.Rob

This one was a fun project, haven't done an AMC in about 20years. Customer is a Jeep fanatic and wanted a good build with about 375hp. Customer supplied the cam and intake manifold and the core 360 of course. After doing some research on these and some measurements rotating assembly was decided...

Because the .484" is a POS and there are hundreds of better options. J.Rob

I see ZERO criticism in my post and ironically it WAS filled with valuable tech. Speaking of sharing tech-- I have shared tech (info) umm, literally hundreds if not thousands of times. Sorry for hurting your feelings. J.Rob P.S. I was "sharing" what I went through battling chatter and was...

I don't have chatter problems when cutting but rigidity is of the utmost importance. The machine you are using and it's column design/fixturing and spindle size needs to be as short/stocky and as large as possible. Then there's the tooling and cutter geometry. You absolutely need carbide pilots...

I know Eric personally and he is a very honest and decent guy with morals and knows how to keep B.S. out of his life. J.Rob

You're gonna want a steeper top cut eventually.....Also too much chatter for my liking, finish with a stone. J.Rob

I'll quote myself just to launch into a memory from when I was fifteen years old. I had just moved to eastern Ontario and made friends with an older kid that had a Olds Cutlass with a 265. Yep an actual 265 V8. Sounded great but wouldn't spin the tires on wet grass. His father was a talented...

Be my guest. Everyone is entitled to their opinion--which is what I was expressing. I'll state it again--If your 'teener is running fine then leave it alone and save for a 360 or... Money dumped into a 'teen trying to get it to make the power of a well built torquey 360 is a waste. J.Rob

They are both designed to be compressed --just one will "light off" or pre-ignite much easier which leads to serious negative work otherwise known as detonation. J.Rob
