Just the transom and stringers and interior are shot. But, I have a unlimited supply of plywood scraps, as a buddy works for the local lumber yard. other than that, the boat just needs some TLC. There was a small fire under the dash, too. Anyhow, as it sits, the engine is locked up (boat been left out in the rain uncovered since 1992). Which is ok, because i am highly talented in rebuilding engines and woodworking, and should be good to go there. Here is what I would like to build for power.


Reuse the stock cast crankshaft. It will need to be cut 40/30, but I am not rich, and buying a new crank is not in the budget.

Reuse the stock 3/8 GM rods. They look to be in good shape, along with the bolts after i soak them in marvel mystery oil for a few weeks. I am not rich, so new rods are not in the budget.

The pistons are gonna need to be replaced. I will be going with some used ones out of my buddys 454 truck engine. I am not rich, so new pistons are not in the budget.

That should take care of the bottom ends. I think they will hold up to 6000RPM, or so I have heard. Which brings me to the good stuff.

I Found a used flat tappet cam and lifter set on ebay. The cam is a 194/203, with .398 lift. I plan to retard it 2 degrees, for a little more top end. I am not rich, new cams are not in the budget.

I am going to keep the peanut butter port heads. I have seen, i mean heard, they can support 700HP. Probably just derust them and throw a couple shims under the stock valvesprings, since i plan to turn about 6000 wot. I am not rich, new heads are not in the budget.

Which brings me to my question. I am in a real pickle here. I am really undecided on which route to go for an intake manifold. I have seen, i mean heard, that a dual plane will be the way to go, as long as i am under 7250RPM. Just not sure. Either that, or my buddy has a single plane weiand intake that he would give me if i mow his lawn. I am not rich, so new intakes are not in the budget.

If you guys can give some thoughts on this, I'd really appreciate it. By the way, my total budget for this build is 672 dollars. I would like to show everyone you dont need to be a spoon fed rich boy to make some BIG horsepower. Which, btw I am shooting for 650-700HP on this build. Keep in mind, I am looking low end TORQUE and MIDRANGE punch. I think when i am all done, I'm gonna be embarrassing quite a few of you big shots with your Fountains and Cigarettes, especially when it gets rough. The liberators are a deep vee. Any thoughts?
