I have a long thread going in the V-drive section looking for suggestions for my 428. I thought I'd run it past you guys, didn't know if everyone watches all the sections or not. Here's the link:
I have the boat home and then engine apart and was hoping to run some more information past you for any suggestions you may have.
As I mentioned before, it's a 428 block (C6ME-A with the A welded in behind the flywheel) which tells me it is a standard 428 block. The Heads are C8OE-N, which is the 428 CJ/SCJ heads. The heads have the 4 exhaust bolts and the airpump ports. Stock rods (C6AE-C) with ARP bolts. Pistons are TRW 2245F, which I beleive are forged 9.5:1 pistons. I can't find anymore information on the pistions, i will have to go on a TRW forum and ask some questions. The cylinders are bored +0.030", the crank is 20/20. I had a lunati #00054 hydraulic, I have the cam card but I'm thinking it's irrelevent since I don't want to re-use it. I have been using an aluminum interceptor manifold, I have a new Dove manifold that I would like to use moving forward. I have a DUI HEI ignition, 22 degrees at 3400. I'm running a 750 double pumper holley, this could change but I'd like to stay with one carb if possible.
The boat has a Casale top-loader V-drive with 18 over gears and a crappy 2 blade junk yard reject prop. It also has an 1-1/8" prop shaft.
Here's what I'm thinking about doing, let me know what you think. I would like to re-bearing and ring the bottom end. Specify a new cam and lifters. Get ideas on the heads, what can I do with mine vs the edelbrock aluminum. Will they flow more or is the difference mainly in the weight? Can use some education here. I beleive I need to change the gearing, Joe Shelfo says 12 degree and I'm good to go with that. Anyone know where I can get a set of 12 degree gears for a casale top loader? I also intend to change the prop. The boat should feel a bit different.
The boat ran 65 on GPS porposing like crazy, it just couldn't seem to stay up on top of the water. I was only getting about 5200 RPM, hard to tell exactly because the needle was jumping around so much due to porposing.
Here's the question of the day. How do I go 81 MPH?
Thanks in advance for all your help and suggestions. DB
