!!!Project 80 Ski!!!

racintj, did not chine in on this issue as i was not going to be the one to piss on his parade.
The cam and induction system will work great for a 1/4 mile car running 4.56 gears, for a short time .But soon MR. Squeeky will come to call,bottom end failure.
I see lots of issues,rotation I am not sure of,cam too muh bump,carb too large, incorrect rotating assy.for said RPM's,and largly understanding how a boat engine works VS car motor immense. But the proof will be in the pudding.
If he can prop it afterward that alone will be a story for this site.
If my prop math is correct;
     If the motor will pull a 13x14 /6000rpm's =68mph
that will be a fast C/C....good luck..boat dr

thats a stock 351, 6000-rpms not for long, Boom!!

Sorry about your Mom, and congrats on doing something to remember her.

I'm not sure how you are positive that it is standard rotation, double check and triple check that this is the case. Are you just going to put rings in it if the cylinders check out? What is the chamber size on the RPM heads? 750 is too much carb for the 351 in a ski boat. 351 ci. at 5500 rpms, with 100% VE (volumetric efficiency) is only 560 cfm. I'm suprised doc didn't jump on that. What kind of lift, duration and overlap are you running? Solid lifters, I guess you like adjusting valves.

Figured you had to be single. You are taking on quite a job. As you can see...guys here love these threads...me too...I just don't understand what all you guys are talkin' about.


Being a Marine must pay well these days...as it should.


john

SRT8...Are you going to rebuild that motor or are you just going bolt all that stuff on that motor, because I have a new set 30 over, keith black pistons for sale if you need them!

boat dr, again please pardon my ignorance...I understand the rear seal and cam being directional. I don't understand the piston rotation part.

Thanks

Not my intent!

I understand RH and LH...you guys cleared the terminology up for me a while back

However it's put, both my boats were RH...opposite a car...clockwise facing the stern

Backfoot asked if he was converting to standard rotation. I took that to mean going from RH to LH. I asked because I thought all of the older CC's were RH.

FYI only...my 79 was RH and so is my 88; Did they put LH motors in 'em back then?

I read all the threads on heads before I made my purchase and it seems to me that I will be ok with raw water on aluminum heads. Especially if I flush the system periodically. And considering the limited # of times my boat will be on the water I think Ill be fine!!!

Its and 80 so the motor is already a standard rotation. CC didnt change that until 88

I call that stuff gingerbread, watch the gear drive they dont like high RPM's

Nate, looks like quite a project. Definitely keep us posted on the results. By looking at the cam, I would assume that you're converting this to a standard rotation motor?

with shipping about 1200... they're only 1.90s. The 351W has notched pistons stock BUT I wasnt sure that it was a deep enough notch to facilitate 2.02s....So I played it safe. I have roller solid lifters, and roller rockers on the way. MSD ignition and Crane Fire Ball Coil.....Ive been trying to contact the doc about the Hi-Teks, someone posted about him getting a good price. Thats the next investment.

Nope....HAPPILY Single!!!!!

yes it is the Holly 750 cfm Marine Carb....Thanks for looking out though
