who makes gear boxx for 4.3 chevy

W.T. doea someone make one and stock 4.3 what cam and intake and carb would ya prescribe.

small talk last night about firtst boat trying to work with what I got for first boat 12.6x7 glass hull pancake cage 2 single seat. looking for advice from the motor Gods.....
 
Either the Stinger or Rotator will bolt right onto one! I have built a bunch of them motors for airboats. They are cool little motors and can make some power we were up in the 400HP range with them. Make sure to run a 2.68 ratio and run more came then anybody will tell you to. I learned that from a guy who use to build Grand National V/6's Remember all the pistons and valves and small parts are the same as a SBC!
 
thank ya, I thought but thats when I usually get in trouble.. 4.3 is a cut off 350 but wasn't sure if gear box would bolt now I know.. Do ya work on boats in cocoa or cars I see you and Felber building big engines.. any way goin to look at 4.3 tomorrow suppose to run and the price is right I just gotta put it ... might wear ya ears out if everything comes together...
 
I have one complete nasty 4.3 left to put together anything else I have left over you can have! I might have a pic from a few years back a 375HP I built with a gearbox on it! The owner would only run a 2.38 so it only has a two blade power shift on it!
 
Here is a pic of a Rotator on a 4.3 V/6

p.s. Iate up a few O540's with it and a nasty 180 with N2O too!
 
Thanks for all the info I believe I can go to bed knowing I might be able to do something with a 4.3 plus I don't mind p^^^#*^g off a few a/c motors if I can get this thing set up right . good night W.T.
 
Boy do I feel dumb I just happened to look at your web site. I/m 100 % sure it will be car motor/gear box 4.3 just something different




HAVE A GOOD NIGHT.
 
The 4.3 was a good platform the only reason I stopped using it is because the LS motors came out and they are even lighter! Those V'6's can push a boat real good! I had fun with them. Are you going to go thru the motor or are you putting it on the boat as it is!
 
W.T. If I can sell or trade my fishin boat and tax time =good glass hull+4.3+gear box=wahooo

probably gonna have to replace at least bottom end like i said I aint no mechanic but seeems to be place to start solid bottom and add along the way. Point blank when I get cash in hand I will come see ya for a mild (budget 4.3 hahahaha they don't go together do they)...

give me around about price for solid motor+gear boxx 2.8 so I know about what to hide from momma.LOL[/b]
 
I have been toying with the same idea... I picked up a 96 4.3 that needs to be gone threw. However I looked on Jegs site and only seen a very limited amount of aftermarket cams (1 or 2). Where is a good place to get a radical cam from?
Thanks
 
I aint real sure done the same thing..I guess W.T. would know what parts are available but if the price is right LS motor but I really like the idea of a 4.3.. on 12ft. glass I guess I need to quit wishin until I get my tax return or boat gone
