Wow thanks for the response. Gotta start looking for this stuff now.
No offense takin' Oletrucker, if you saw the shape of this truck you'd probably be happy I was building a Rod out of it!
Bigredtrucker, you must be from Hondachopper, what's you name over there? Yea it's got an 836 from LRT, cam, dual carbs and a bunch of other stuff.

It's a fun ride.
Thanks,

The engine that Erik posted would be extremely reliable with the roller cam and low RPM's. If you are looking for a little more power with a little less reliability of course then go with the AFR setup.

Hmmmmm.....this is tough to decide.
I found this site today and read through it, priced everything out in test #34 to $2500, and then maybe get a new rotating assembly wondered if cast would be okay for about $6-800. Might be a little too much though.

Whoops, fogot the link, here it is.
The truck is just an engine doner $275, It's not light at all!! The car I'm putting it into will be though.
Keep it coming, thanks,

Test 34-Vic Jr. heads, COMP XR280R cam:
Max 441 tq, 504 hp
Avg 404 tq, 359 hp
Next we tried Edelbrock's Victor Jr. heads @ 10:1cr, (64cc chambers, 215cc runners, 2.08" intake valves, 1.60" exhaust valves), with a Vic Jr. manifold and one of COMP's Xtreme Energy Street Roller camshafts (242/248 @ .050, 280/286 adv, .600/.606 lift w/ COMP 1.6:1 rockers, 110 LS), and a 650cfm Mighty Demon 650 carb. The results were 504hp and 441 lb-ft tq!
...The stock bottom end of that motor you have would be at it's limits. If you go cheap you can buy a Scat cast steel crank and i-beam rods and forged pistons for about $1000, it will handle the power. This isn't the lowend torque monster that you were talking about though.

Yea your right I'd rather have it down low. So ya think that AFR set up would be better. I was looking at some of the top end kits Summit racing has also, still not sure.

Okay tell me what you think:
AFR heads-180, 64
http://www.jegs.com/webapp/wcs/store...56115_-1_10187
Edelbrock Performer 600cfm carb
Edelbrock Performer Air-Gap intake
Comp Cams xr264hr-10
Scat Rotating assembly (10:1 comp.)
http://www.jegs.com/webapp/wcs/store...71035_-1_10759
Comp Magnum roller rockers and pushrods
Lifters ?????
All this is about $3800 . I figure I could save a few dollars here and there, but unless I can build a strong engine for around $2000 I figure I might as well go for it. The Dart heads seem to be within $500 of the AFR. The carb is for ease of tuning, and the rotating assembly is only if I don't have a forged crank in there already. That Cam costs a fortune by the time you get the lifters in there ($460 for rollers, unless I'm missing something). I keep reading that Roller rockers will give 15-20HP gains, so $175 seemed OK.
Any more input to this would be great, maybe it's going too far. I don't even know what the stock HP/Torque is???
Thanks for your help, now I got to go work some overtime!!!!!

Weight I don't know what it will be, I haven't thought about gearing yet, I'll have to see if the rear end off my 1/2 ton will fit properly, it's an auto th400 that I have so far. I wanted to get the engine done while I wait for my suspension parts. I started to think that will be too much and it wouldn't hook up anyways. Is one of the Edelbrock power packages a better way to go.

I figure all I'd need is pushrods, rockers, carb, and then a rotating assembly. Probably about $3000 complete.
Man, motorbikes are easy compared to this! Maybe I should have asked for a budget build.

I'd imagine I would gear it low as I don't need to go 100 mph, just enough to make it drivable on the highway. I'm not sure on stall speed but I think I can work on that later, not sure what stock would be.
on small cars yes. but fat fender cars are pretty much the same in size and weight as the donor car. i found s10 brakes work great on fat fender and pickups. a deuce will just need manual brakes...
Time for brakes
