Gen's Shop is right behind the Clinton Napa on Rt 1. Small 2 man band...
He builds mainly short track sbc, but did a set of 540s for Ocean Performance last year.
I had him rework a set of heads for me...

hey guys, pat my engine is 2 seasons old now,it was a brand new gen 6 502/502 that i bought thru affordable marine in portland,i know jim down there thru a friend. the engine came from liberty marine in mass. it is a full marine motor with crane cam169611 (576-598 lift)and all the springs,roller rockers ,etc are crane. it has an aluminum "zues" hi rise single plane intake with the bronze water passages,and a custom nickerson performance holley carb. exhaust is thru lightning headers. pat, i measured my x against your pantera,and mine was 2 inches deeper. from an older forum i posted ,the pantera guys said my propshaft should be no more than 4-4 1/2 inches below my hull,mine is 7 1/2! this boat originally came from the factory with a 350/alpha set up in 1990,so i don't think it was set up to be a rocket ship. i've really got my hopes set high on this x dimension change. it is a rocket out of the hole and midrange,but top end it feels like its being held back,wot is 48-4900,raisng the x should give me 2-300 rpm easy,which should put me 52- 5300 rpms. i also just bought the thunderbolt 4 module for an hp500 carb,i was running my old 350 one , hopefully all the little things will ad up,i know i've got the makings of a fast boat,its just getting the set up down perfect.

Condor24,
Sounds to me like you have done your homework.
Your boat may have had an Alpha SS drive, I think they were shorter... My Superboat X and Pantera X were about the same.
Your engine has the HP500 cam and headers so you should be making lots of power.
If I can help with anything, let me know.
Post a few shots if you've got them.
As far as I'm concerned, your welcome here on the Superboat Forum...

i appreciate the response pat i will be in touch with you soon on that motor mount,i've got to raise the motor anyway so i might as well upgrade . i 'd love to check out your boat when the weather warms up,sorry i dont have any pics to post,my boat will look completely different this season anyway,talk to you soon,bob

Pat,
I didn't know the name of Glen's shop was GCR. Glen seems like a good guy. I have a 67 396 Camaro that I was having a problem with, I went to his ship to pay him to do a quick job for me. He did it on the spot and refused to take any $ from me. I've sent him tons of business since. I'm going to need that 396 rebuilt soon, he'll get the short block.

BTW, I was looking at the river this morning... it's pretty damn high. Can't wait to get on the water!!!

Bob,
Come on over anytime; I'm exit 5 off rt. 9 so 30min at most.
SS930,
Glen was recommended to me by a marine mechanic friend and a car racing friend. Does seem quite knowledgeable for a young guy.
The river is a swelling, snow up north is melting, spring is 10 days away...

Pat,
I'm curious, do you know if the X the same on the regular Superboat hulls as on the stepped hulls?
Thanx- Sd

Hi Sean,
What's Up?
Supercharger and full hydraulic this year?
I don't know about the X dim. on the two hulls?
Anyone know?

X DIMENSION. MY 30 HAS THE PROP SHAFT 2 INCHES BELOW THE BOTTOM .AND THE BOTTOM IS A TRIPLE STEP.THE NEW X WILL BE EVEN WITH THE BOTTOM IF I MOUNT IT RIGHT.LETS SEE IF IT WORKS.

hey pat ,i measured the distance between my stringers,looks to be approx.30 inches, how wide is that engine mount you have? i talked to a local race car engine builder and he is going to come over and measure my cam lift and tell me what i have. i have a bad gut feeling this isn't the hp 500 set up i ordered ,but a 415hp 502,guess i'll know soon it would explain why my topend results aren't adding up,talk to you soon,bob
