Lol sorry buddy but man we learning a lot hahaha

Those normally pretty tall no?

You needed to do that,^^^^^^^^ remember what you said in post one ?? that was really uncalled for

You probably saw this.
 

Can't confirm but thought I'd post.

some but not all.

Yes Billy's boat, he's got 3's that's 2" shorter X, then engines he had were a tad over 700 also... He offered them to me when I started building mine... Hindsight.... Ya well haha

3's aren't 2" shorter than trs

Same? I was told they are, then the 3a and 4a is 2" shorter over a 3..?

To see 80 with Trs you would not do it unless maybe you have 800+ N/A HP, and at that point your lucky if the Trs lived enough to get it there haha

A buddy years ago had 830 hp in a scarabIII WITH TRS... Struggled to see 82, and it's way lighter then a mistress... Personally I think the huge bullet and depth of the drive is just too much drag at 80+

4A!!!?? No such thing.

I wanna say a 3 is 1 or 1.5 shorter than a trs. A #4, is about 5.5", shorter than a 3/3a.

Ssm 3 is 24.311
Trs is 24 7/8 iirc

94 top gun with 700's and trs did 81

Top gun is faster hull then mistress, my chits a SLUG!

I'm not up on SSM drives, just what I thought oops

Nope No 4A. However some had small shaft 19 splines and they were upgraded to 26 Spline. Parts were always tough for the 4's because they just didn't make many and then stopped. Short span of years.

Yep. I have small shaft 4's. They use the same lower gearsets as the big shaft drives if i recall. The upper gears are different due to the polygon vertical shaft . Some 4's came right from merc with big propshafts

40 Hawk did 82 on its best day with those motors IIRC:daz::coolcowboy:


Maybe Tim should buy the Hawk

Ran 84 once for me and I believe Kevin saw it there too with prop work. I cheated with 55* and good gas. Imco's don't make it a fair comparison.

But the 40 with Konrads runs 75 with 630HP 540's. For Sale too!

The 40 hawk had a 22 deg deadrise if i recall.

Rode like it too...

Tim, just buy my engines and install, boom 95mph guaranteed.... Maybe you will get more hours out of them than me.....

My mistress needed some engine compartment height so I through bolted an aluminum I beam around each hatch and re hinged the top. I put electric actuators on them to open close.

You can see the I beam in the picture if you look the engine. I needed that with the Flame arrestors and when I thought I was going to run carb spacers.

That was one of the nicest mistress's ive seen ...cool boat

His mistress made me want one more then ever I loved that boat

Cig rocket, any clue where it is now?

Yes, I believe Texas. It went to LOTO from me originally. And got lots of use, I believe 600 hrs. And then was sold to a guy in texas, he is a member of offshoreonly, I can't quite remember his screen name.....maybe he will chime in

When I sold that boat the economy was failing and I had a Top Gun I wanted to buy. That was a fantastic deal when I sold it. The guy in LOTO like I said ran the piss out of it. Konrads and 700s. Just changed the oil and it went. For the price that it cost to get a mistress to that level, it was a steal.

custom cams
 

I am a few weeks away from my 540's being finished. similar to Tim, Bob M. spec the cams and heads. afr 325 114 cc the cams are 242.2 664 on intake 247.1 656 on exhaust flat top JE pistons, merlin 3 blocks zero deck and the head gasket he set me up with from cometic is .027. I am running Nickerson 4150 on merlin single plane intakes. carbs flow 994 CFM. as soon as the engines are complete they are going to Nickerson for dyno and tune. I will be happy to provide the results here. I can find out from my builder what the final comp. ended up, our target was 9.8 :1. will post more info as I get it.

Zero decked, and .027 head gasket?:bestwishes:

Curious to see results....

Cam and Heads
 

like I said, I will post for sure where the final comp. ended up, think the pistons were 10 in the hole but will verify exact numbers. motors still with the builder.

Definitely won't be any carbon on those pistons

Diamonds.

Big difference !

Zero decked means piston is at the deck. Zero means zero.

Full Force - I'm going with 677 :party-smiley-048::bananalove:

Never gonna happen on Nickersons dyno. After the first pull he's going to tell him the cam is all wrong and he has a guy down the street that custom grinds his cams for $500. His custom cams are actually $250 Erson cams... It will make 100hp more on his dyno with the custom Erson shelf grind.

Sounds like a small block.

Do yourself a favor and take a new Holley with you for the dyno session. They are worth 30hp over Nickersons best ported and polished carbs.

I'd be pretty thorough on the measurements, and certainly account for and measure piston rock. When I am putting together an engine, I measure the piston to deck height with a deck bridge and dial indicator after the shortblock is assembled. once those measurments are taken, THEN gaskets are ordered.

IMO, the benefits, do not outweigh the risks of playing with extremely tight quenches, on a bbc, unless you are building an all out competition engine. If the piston is at 0 deck, .027 is playing with fire, even with a steel rod. Staying in the .040-.060 range, is fine for a N/A build, and most forced induction builds.

I would imagine that Bob M, spec'd those gaskets, assuming the blocks were being zero decked. I don't know how anyone would know the specific blocks deck height, without physically measuring, if in fact, the block was anything other than zero deck. Unless they are virgin blocks from world products, but even then?

Wouldn't be surprised. Most combos make more power when the madera cams are tossed.
