Those numbers would be pretty easy with a Big Block, and it'd be relieable. Only draw back is that Big Blocks = $$$$

350 lbs.....so it'd be just like having my girlfriend in the truck vs. not having her. Not enough to worry about. I'd much rather have the Cummins over a beefed 6.5. It has a lot more potential.

ok what girlfriend and since when would you give a chick that weighed 350 a second look? you'd be too busy gouging out your eyes

Those are impressive numbers aren't they. Now, the 425 that I am putting in, I haven't really seen any numbers for it but the possiblities are intriguing. Start out with better than a 4" stroke. Port polish the heads. Bump the valve size a little. Bump the compression a little. Nice torquey cam, Who knows. And its real close to the weight of a SBC. Even lighter than the other two caddy's.

Kevin, your engine did do quite well. What was it and where did you get it? You build it yourself? How are the #'s a little lower in the range, say 1000-3000 rpm? I often feel the need for a stronger pull than my engine provides in this area. Your price and compression sound nice for sure.
Alan, I also like the stats your project is putting out. Low tq peak and higher hp peak. Sounds good for the crawling as well as the throttle happy hill climbs. Do you have the rest of the figures off the DD results?
Rjfguitar, those #'s just don't quite seem to match what I had in mind. A little to high in the range.
As far as the 6.5 goes the cost is just so much higher than it would be compared to a gasser of the same output. I am a fan of diesels but I just don't see putting one into the trail rig as good of an idea as having one in my future tow rig

I don't really like the weight of a BB due to the fact that I will end up running a winch and a heavy duty bumper and the caddy engines would be nice but a pain to make work with my manual which I refuse to give up. Thats why I am looking for the sbc solution. Simple and relatively cheap. /forums/images/graemlins/waytogo.gif

It's not that hard at all to stick a sm465 behind a Caddy. My neighbor put a 5 speed Clark behind his 500 in a '79 K30. He's told me before how he did it but I forget the details.

This is true, but WEIGHT is a factor. And the 6bt's are heavy SOB's. I really like the idea of a built 6.5, but I doubt ill ever swap one into my K5. Im still on the hunt for a 4bt for my K5, it would just better suit my personal needs for my truck than a 6.5. I have been tossing arround the idea of a 300hp 6.5 into something else though, something much smaller /forums/images/graemlins/whistling.gif

IIRC the Caddy cranks do not have a pilot hole driled in them, so you'd have to do that. Not sure which flywheel would work either. BOP bell's for the SM 465 exist, and if they're too hard to find adaptors are out there for sure.

The Big Block is about 110 pounds over a Small Block. I was going to dump my 454 and go with a stock Vortec 350 untill I found this out. With headers , AL intake, and a few other things. The weight difference gets to be small. You can also build a Big Block and still have the torque. I run a .520 lift cam in mine and still have plenty of torque. I had enough to gernade the front end off of idle even with that cam. My plan now is to cam it way down, go to an AL water pump and radiator, and then go break it again. /forums/images/graemlins/grin.gif
If you can find a good deal on a complete truck or something with a big block that would be great. If not, anything from a 350 to a 400 can be put together pretty good.

[/ QUOTE ] Well, I reread your post and noticed "at the rear wheels." Many will argue with this but I think you are going to have a hard time making a SBC idle good and have lots of low end with trying to make 300/400 at the rear wheels. That is like 375/475 at the crank, which is pretty healthy for a SBC. If you are looking for low end at those power numbers I would be thinking about a BBC or caddy. I have a hard time seeing you build those numbers with a SBC without the cam being large enough and getting the RPM band up a little higher than you would like. Maybe that merlin 454 SBC could do it. /forums/images/graemlins/dunno.gif
I have an idea!!!!! /forums/images/graemlins/grin.gif
How about a mild 350 or 383 with a mild cam that will make nice power in the lower range RPM's and for higher RPM power that you want for hill climbing you could add NITROUS! /forums/images/graemlins/thumb.gif Even only a 75HP shot on a mild 300HP(at the crank) motor would really help you take advantage of both a low end chugger and high RPM hill puller when being squeezed. /forums/images/graemlins/peace.gif Kind of a Jeckle and Hide thing. /forums/images/graemlins/histerical.gifI might run a little juice on my 406 for some mud racing.

From what I understand is you have to have a pilot bushing machined to insert in the back of the crank. The crank is bored but apparently nothing fits right. /forums/images/graemlins/dunno.gif As for a flywheel your pretty much stuck with buying an aftermarket I believe. The bolt pattern is all wrong between the two and don't think any alteration of a chevy crank would be feasible but can't say that I've really looked into it.

Paxx, I really don't remember what the numbers are for sure at lower rpm but here are a few more specs I did build it myself (you can do it a little cheaper than I did.
391 cu. inches
2.02 x 1.60 dart Iron eagle heads
3.835 stroke crank
4.030 bore
comp xtreme cam (third grind .480 lift can't find the # right now)
GM stage I rods.
What I do know is that it pulls hard through the rpm range
pulling a 8,000 load on a trailer up hills, down hill driving down the street empty cruising the mall or whatever you want. Plus it will really set you back in the seat when you leave the stop light if you want. My truck is heavy and I get about 10 mpg at 65@ 2800 rpm.
