Ideas and opinions on Goodwrench 350

Hi, I just picked up a Goodwrench 350 crate motor to put in my 84 1/2 ton shortbed, it is replacing the stock 305. I have the 700R4 tranny, 208 T-case, 3:73 gears, 4" lift,33" tires. Anyone have any good suggestions on add ons or build ups for this engine ? I'm going to run a Performer manifold, a Holley 670 CFM 4 barrel (For now) 1 5/8" headers and dual exhaust. I'm thinking about tossing a Comp Cams 4x4 extreme cam in it, anyone have any expierience with these ?

<font color=green>Hey, you're copying me![img]images/icons/laugh.gif[/img] I got that motor a couple years back, put in a Comp Cams "K" kit with the 258(?) Extreme cam, Heddman headers, 600 cfm Edelbrock carb, Performer intake, Summit cheapie high voltage distributor and a humongo air filter. The thing has been great to me, it'll light up my 38s with to tall of gears (4.09s) and a manual box with no brake used to get it started (Not that I do that very often...[img]images/icons/tongue.gif[/img]), and it's been dead reliable, even when I've flog it. I onl;y have about 10k on it, but alot of those are hard fought miles in mud and sand.

Sounds like a good set up to me. The only thing that i would be wary of is the tranny. I know that around 85 or 86 (i think) GM corrected their problems with the early models of the 700R4. As far as the engine goes, sounds great.

Re: Ideas and opinions on Goodwrench 350

I'm not sure what would happen to the warranty if you change the cam, but if I were to use a Goodwrench 350, I would use a Competition Cam Xtreme 4X4 cam. I'd use a TBI system, with larger throttle blades, on my new Goodwrench 350 also, but then again thats me[img]images/icons/smile.gif[/img]. I'd be more in favor of using a Quadrajet instead of a Holley. A calibrated distributor can make an engine run very nice. I think I'd also use an Edelbrock intake manifold, but I'd use the Performer Air Gap. I also like headers, but I'd most likely use Hooker Headers.

It sounds like a good combination. I would go with the comp 12-235-2 cam. I would also go with the performer manifold unless you get a bigger cam then I would go with a air gap and a sloppy (higher stall speed) converter.

Re: Ideas and opinions on Goodwrench 350

Thanks for the replies, the trans has been rebuilt to newer specs! I'm thinking of throwing on a set of the Vortec heads when I can afford them too! Distributer is a stock hei that has been rebuilt with Accel goodies, and Champion Truck Plug wires. The Holley is a stop gap till I can afford another Edelbrock Q-Jet, they are a bit pricey! Or maybe the new Holley Truck Avenger, they are supposed to be full of all the good stuff! Comp Cams reccommended the 235-1 cam to me, it has a little milder lift and duration, good from 600 - 4600 RPM, would the 235-2 be better in the 350 or would I lose some bottom end and milage ?
