Yeah Pat I bought one of those Bowie 4.3 cast iron blocks against my partner's advise from a bush team when they stopped using them.It was a ruff casting with nothing done to it.No holes,nothing.Talk about expensive........I had to turn in my first born<well he ant worth much so it was a good deal-LOL>to finance the machine work needed and then the parts....... common pin crank,I had to be out of my mind.In the end,holding it back it ran in a chvette ran like a clock 10.90 every time.

Man, I read the info on the link---now Im more confused than ever-----it seemed such a simple idea in the beginning!!

But, to go on a saturday nite cruise in a lil chevy II, park, open the hood for all to see a cute lil 6 popper all dressed up like its big brother. With a mild build and a little cam, she ought to run adequately with a little bump!

you do not have to make it hard just look for a gm roller cam engine .use some marine parts or buy a intake marine cam or a roller cam .abit of head work and some CR and you will have a runner .i all ways used 350 pistons in the 4.3 was cheaper then buying 6.there is a evenfire and odd fire engines new one pc seal is the block you want there not hard to find i would look a 1990 the newerVtec engine may have better heads you will have to find a intake or drill the heads a check port runner match up

Scott Sehr's shop sent me this link on a 229ci v6 they did - 503HP, 474ftlbs sounds pretty mean, engine's headed to Hawaii!! Scott's a great guy in Sioux Falls, SD.
