ok once again my 77 ski is in the shop due to a stump. My insurance company gave me 3k, there are some scratches and a hairline crack under the stern of the boat. Im not going to fix the scratches until the winter and I intend on doing it my self, So with the extra cash im going to buy a cam and intake. Right now I have a stock 351 with electronic ignition installed and gt40 heads. what intake will fit under the engine box without height being an issue. what cam do i buy and where do i get it. I have only used lunati cams in the past, I really dont know of other brands. Thanks for any advice.

I bought a Clevite cam. Tall intake manifolds are for top end performance, not bottom end.

for the money get a performance products intake off of ebay. It's a reproduction of edlebrock's design basicly at a fraction of the cost with a crossover water passage the edlebrock doesn't have. I'll be getting a chrome version from them when my heads are done another thing you cann't get from edlebrock either. I use a comp camscam like a coule of others it's custom ground because of the reverse rotation, others have used the clevette and someone else found a pretty good source as well I believe it was Tim that did, TBJial or something like that. just don't get too crazy unless you know exactly what the lift rate of your valve springs are otherwise you'll be fixing the heads. Get a high output coil as well be carefull with the blaster II on the mallory dist they say it will burn it up, the resistance is mismatched for the electronics. I use tha mallory pro series marine verson paul has an automotive version of the same coil on is 62. Your going to have to re-jet the carb once the cam is in to so that you don't lean it out and burn a valve but it's pretty easy to change jets think you'll need 72's.

intake satin finish
a polished version runns about 175 a chrome version runs just over 200. a cast edlebrock performer runs a little under 180@summit and for that price you can get the polished performance products. |

shouldn't be an issue, I believe there is a inch or two of clearance depending on the arrestor you have.

You were close, 79- at least you remembered my real name!
I have a Weiand Stealth intake that I am happy with ($190 from Summit). I have read its a better midrange intake than the Edelbrock Performer- I actually bought both and chose to install the Stealth. The prop slip coming out of the hole acts like a torque converter on a car, making real low end torque less important than some people think (I get an instant 3200RPM). The Stealth is about an inch taller than the Performer though, which is already 1.5" taller than stock. Better check your clearance before you decide on a manifold. I installed a cam from Cam Research and have been happy with my results. They only do Ford cams and they are familiar with ski boats- they really impressed me with their knowledge. I almost bought a Comp Cam but after talking with these guys I purchased from them on the spot. Their prices are reasonable as well. The only drawback is that they dont have any reverse rotation blanks. Not sure if they can grind one if you can source the blank, but I would give them a call and see what they say. |

Question?
Is the bolt torque on a Alluminum intake the same as a stock cast intake? I think PCM list 32 lbs for intake manifolds. Just want to be sure. Thanks for the help |

If you guys like Crane cams, look in the cam section of the Summit catalog and search for Summit cams. I found out that they are made by Crane and are usually much cheaper because people think they are some off brand. If you ask them who makes the Summit line they wont tell you and i happen to no a inside sales guy who works there plus on the installation book you can see a crane box in one of the illustrations. I havnt had any problems with thier cams
