Boy, I would certainly be interested in that pan!

Is this something I should attempt to do with my boat engine?

Here is the specs on the Isky cam... Cam Style: Hydraulic flat tappet Basic Operating RPM Range: 2,000-6,200 Intake Duration at 050 inch Lift: 221 Exhaust Duration at 050 inch Lift: 221 Duration at 050 inch Lift: 221 int./221 exh. Advertised Intake Duration: 270 Advertised Exhaust Duration: 270...

Just my luck, the Diamond pistons are backordered as well! At least that gives me time to play with rod lengths. I got a hold of a guy that converts Mopar big blocks into boats. He claims to run an Isky 270 Meg Hydraulic in his engines. Does anyone have any experience with that cam? Is...

Yes, after reading a bit about E85, I have also come to conclusion that it would create some troubles down the road that I don’t really want to deal with. Locally, I can get 91 non oxy fuel, so that is what I am going to shoot for building this engine. As far as the cam, I was once told that...

Well, the plans changed a bit. I had ordered a set of Icon pistons from Jegs. They stated that they would ship directly from the manufacturer so I would get them sooner. I have gotten three different shipping notifications, and they keep backing up my ship date. My most recent email received...

Alright, took the advice of you guys, and ordered the IC839’s. Guess that leads to another question. What ring set should I run? These pistons have 1/16-1/16-3/16 inch ring pack. I have run Hastings rings in a couple of bikes, but never had the chance to go fresh with a V8.

Wow! Lots of power with that E-85 set up! After looking over the compression numbers on the Mahle pistons, I come up with 10.37-1 compression. I should think that is low enough to safely run pump gas.

Don’t know for sure, but this barge will get pulled out each day, and there is a good chance that we won’t be going very far. At this very point in time, all I have is the block. Everything else is up for grabs. If E-85 is a good option, I think the Mahle piston is what I would go with.

I am looking real hard at the Diamond racing piston with the -12.5 dish in it. Seems that would give it 10.5-1 compression with my thoughts of what to put on it. I was filling up the commuter car the other day (diesel), and happened to look over at the E-85 pump. That got me thinking, wonder...

Thanks for the reply! Just wanted to be sure that I understood that to be correct. I am currently waiting for a reply from Mahle to see about custom pistons, and if they say no, then I think I will go to the diamond piston with the -12.5 dish in them, and go with a 6.7” rod. Need to get some...

I have been working a little with compression ratio calculators, and wonder of if I am putting in a number wrong. FYI, I am using Diamond pistons CR calculator. With a flat top piston, should the number be positive or negative? Seems like the logical thought would be to make it positive...

You are absolutely correct...this isn’t a race boat. So, it would seem that the Mahle piston with a 1.475 CH would be a good option. I should think it would then make more sense to go with the Edelbrock head with the larger chamber, and put a little money into cleaning them up vs opening up...

Yes, I had wondered if Andy Highlighted that one, or if that was just what line it was on when he copied it. I have read a little bit about the rod ratio of short rods vs long rods. I know Andy had said the shorter ratio would be good for a pleasure cruiser. My boat originally was designed...

Andy, I will whole heartedly admit that you and IQ52 and many others have forgotten more than I know when it comes to building engines. I was setting up something similar to your spreadsheet last evening, but ran out of options for this list. Hopefully I can continue it today. Thank you...
