I have a 350/330 engine in my Minx that I bought from a guy years ago. It's currently in my Minx. I have the complete parts list that he used somewhere, The only thing I could find offhand was the cam and heads invoice. He had built two of them. It had 30 hours on it when I got it. I put it in my F20 Formula originally, I just recently put it in the Donzi. It has incredible midrange, and idles great, when the carb (Edelbrock) isn't full of crap in the idle circuit. It has a performer intake.

Cuda: yes, I have lots of room around with doghouse removed. Plenty of room to remove damper and cam. My only concern at this time is dropping the front of the oilpan down, just enough to get timing cover out. I believe I can reach all the oil pan bolts but there is not room to get oil pan out to do full gasket replacement.

dont loosen the pan at all to r&i the timing cover for a cam swap. you just need to put on a new timing cover gskt and rtv the corners. use a screw driver to pry the timing cover down to line it up with the 2 locating studs. i've done several bbc and sbc engines this way. no problems, no leaks.

It onlys takes about 45 minutes to pull that motor out, GET R DONE :D Spend some money on some AFR heads, you will be alot better off. I had a 260 hp stock mag.. Built a 383, all high doller parts, around 550- 560 hp. Stock 58 mph. 383 took it too 77.2 mph. its comes out to about 15-16 hp for each MPH and to add to the excitment this is in a 19' 3000lb boat with a alpha drive. 3 years now and not one problem, good oil, shower and it will last. By the way I beat the **** outta this setup. This motor idles around 700-800 rpm and will never load up, I idle through a lot of no wake zones 2-3 miles at time and it does great. On holley's. Bought mine new.. jetted it and have not touched. You just have to know what your doing. if you do go with the vortecs, make sure they have screw in studs, machined for guideplates and teflon valve seals if you are running more lift then around .480"

What you gonna gain with what you have planned?? 3-4 mph... dude just put some flames on the side of your boat and don't touch the motor :D


Nothing like the sound of 6000 rpm and the smell of race fuel :evilb:

For me it was easier to drop the pan some,I had a hard time trying to get the timing cover sealed at the bottom without doing it,I have done it without dropping the pan but it was way easier to just drop it and make sure it was a good seal.

That is the almost same cam I have now,great idle and midrange,it does not have enough for my dart200 heads,I am going custom this winter.

Guys, thanks for the comments on cam removal.

Travis, you are over the top! :D Lets just say, this has to stay a civilized family bow rider.

Get the tallest dual plane intake that will fit under your hatch and that will let you mount your carb of choice without having to use an adapter.
