    Chapman did them, professionals...will hold up great.
    I didn't do the mid section welding etc that you see left that to again pros..only thing I did to that was drill the hole thru the exhaust liner lol...
    Hp they are up there did alot of work ..I was given a really good guess buy someone but it's a guess,
    James Perry did a the machine work porting, pistons etc..
    I did the rest...I haven't had it on a Dyno so can't say.
    How loud.....they are loud with the offshore exhaust and the lowers drilled plus have the 2..5/8" holes at the top of the mids thru the liner too...only videos I have are on the hose really.. have one at the dock when I started break in but we're buried so..
    If you want can get them I think I still have them ..videos

    Unfortunately I do not. It took me several years to cobble together the ones I have. 25Ē units are fairly easy to find as I assume youíve experienced. If I come across a full 20Ē motor Iíll let you know - thatís how git one of mine.

    P.S. if you consider making more cowls or selling the mould let me know - I do glass work too.

    Thanks for letting me know Matt. I think my next project is going to be making a light weight cowling mold for the 2 V8s I have. I donít have a lot of spare time so it will be a long term project. And after all of the effort I put into the V6 cowling mold, I just donít think Iíll ever sell it. If I do though, Iíll hunt you down.

    You mentioned that Chapman did your engine work. Gordon (Monty racing) is not answering the phone anymore. I guess I'm in the hunt for some one the knows these engines. What do you think?

    Finally got ahold of Monty. He was busy with his drag race clients. Had several blow overs to contend with.

    If you want to both crank and direct inject you will need to put a lot more thru the crank than 10 to 20 percent, remember this also supplies lube for the piston skirts. I agree with Gordon to stay at 300 or below for every day use and that power level can be made with all production parts.

    Taylor/Jenkins mid is the way to go for the V6. Unfortunately they are getting hard to find.

    Here is a overloaded question 4 u, any ideas on where to find data on oil metering rates and requirements for crankcase oil injection just like an etec would have? I am considering prototyping Bosch direct injection with these 3.0's in the next couple of years. I suppose the simple answer would be go buy an etec and be done with it but that's not my style..��
