Are your engines enclosed under a hatch??? If they are you can't use those headers. They are water injected not water jacketed.

XCAV, I'm not used to seeing this type of photo content from you:D :D

XCAV8,

That Crane cam you mention in your first post of this thread is a decent enough of a cam for your engine. The 049 casting on your head is an EXCELLENT GM oval port head. The GM 049 oval port head comes stock with a 2.06" intake valve and a 1.72" exhaust valve unless they have been previously modified. Those heads would work MUCH better with that cam if you at least had a bowl/pocket port job done on the heads. You could add larger valves but then there are more machining processes you must do, etc. You will make probably about 450hp with that engine combo.

Tink, Basset did or still does make a double wall header---though they are rare or don't see them much---but I DO know what you are talking about. ;)

these are double wall, water jacketed ,they can be run wet or dry
these were built back when john bassett was still alive....
supposedly the guy paid 9k for them

what you don't like my pics on this post;) ;) ;) :D

XCAV8 If you have any questions contact Jack Boyd. He is one of up state NY best keeps secrets. He builds strictly High performance engins for over 20 years. his shop is un believable. and his dyno is capable up to 2000 hp. He don't advertise. strictly word of mouth. He is about 40 minutes from Albany. I travel up there frequently and live close by to you. I could drop off parts for you if you like. His # is 518-661-6089 , some day we might bump into each other on the river. I'm got a blown 28 scarab called Dysfunctional, I'm frequently at the Newberg area with a bunch of other oso members. get that boat running & join us for drinks.

Since no one addressed carbs. You can use either but I think the 800's might be a little large. They could be jetted and tweaked to work but the Q-jets might give better flow velocity and be an easier tune-but keep in mind I am biased towards Q-jets and have spent a lot of time with them. If you or whoever will be final tuning those engines is more comfortable with Holleys then they will work out better. It really depends on what you like to work on.


......use the Q-jets :D

Hot Boat -- thx for the info ,i will definitlygive that guy a call...
hmmm i wonder how long it would take to do the heads,(resize the valves to 2.25/1.88,) and port etc... ?
i definitly keep an eye out for ya..........

insptech --- thx for the input, i too thought the holleys might be a little much for my set up, i will prob try both....

i was also looking at the Edelbrock 750 marines, don't know much about em,
i would have to buy them ,but the price is right....

i'm putting an order in on tues for all the goodies heres my list so far
Crane PowerMax Cams-- the cam above

Crane Lifter Kit

Edelbrock Performer RPM Air Gap - large ovals I desided to up grade to a pair of these

K&N Standard Carbureted Style Flame Arrestors -- 6 3/4

how long will it take to get this stuff, is there a better place to order than cp in california ??

Sounds Great, good luck!!!

These jugs are nice but the others are sweet!!:D :D
