Title: My favorite game...What would you do?
Post by: GT Jets on March 08, 2009, 10:19:13 PM

I started putting my spare Jet boat motor together for the season today (.030" over 454) and found a leftover set of really nice Speed Pro domes that have like 5 hours on them in storage, the problem is the heads I have (98cc ovals) will make the CR like 12.7:1 :o, fine if I want to run alcohol, but I don't.

So I started looking around for some spare heads and found some big chamber peanut ports and another set of closed that need a guide replaced (101cc ovals) and I want to be in the neighborhood of 120cc for a total CR of 10.0:1, oval preffered but not real picky (I always find the throttle resonse and mid range power to be more desireable with oval port stuff  :screwy: )

So what would you do?

I have enough crap to put together a short block, just don't want to get stuck trying to find some heads...

Looking to trade, swap, buy, sell and then buy to get where I need to be. I will be going to the Good Guys get together in Pleasonton at the end of the month with a bunch of leftover race boat crap that I don't need and may get lucky there, but your input would be appreciated...

I have;

perfect set (still shiney) of Speed Pro p/n L2349-F30 pistons mounted on 3/8" bolted rods ready to rock. (2 bolt block cut to fit these)
built set of  cast #3872702 heads 98cc ovals
trashed set of cast #3964290 heads 101cc ovals (need a guide replaced due to dropped valve)
built set of cast #14092360 heads peanut port unknown cc's (didn't check but they're big)

Also have an Edelbrock performer for the peanuts, also have an OEM cast iron manifold for the peanuts.

I just need this as a back up motor for the jet, may end up putting in the jet this year depending what I find in the 468 in the boat now (a lot of metal in the pan  :banghead: ).

How does it go again? two steps forward one step back!

Thanks in advanced!

I think in the life of a jet boater it goes  (one step forward, two steps back)  :banghead:  ;)

You might also try hitting the Pomona Swap Meet

Missed the one yesterday, but a buddy told me that the one before was packed with sellers and seemed like nobody was buying.  Might be a good opportunity to pick up some deals if you have funding.
