I started with a 90s 5.0 HO block had my local machinist Bore it 30 over, Decked, align honed, and the bore was molley honed. I had to notch the bottom of the cylinder walls to make clearance for the rods. PAW offers a 347 Stoker kit and I upgraded the kit to forged, steel, balanced, Crankshaft, pistons and rods. One problem was that I had the assembly balanced for the later 50oz counter weight, this made a bit of a problem to find Proper flex plate that matches a C6. Bolt on parts list as:
GT40 aluminum heads (M-6049-y303) ported and polished w/ big chevy valves, Ford Raching E303 roller cam + lifters 1.6 ratio roller rockers, Cloys true roller timing kit, Weiand Stealth dual plane manifold, Holley 600cfm, Tuned shorty headers, Proform HEI for ford w/ performace HEI parts, March pully kit. |
| Drivetrain: |
Tranny is G on the plate(automatic), axel is 16 on the plate(ford/3750/3.50). I have a new C6 and rebuilt the front and rear axels and steering componets. The front axle is a Dana 44, and the rear is a Ford 9". I'm going to keep them orginal since my wife is going to be driving it and I don't want her to roll it over becuase it's lifted. Might install a locker kit but that's way down the road, gotta get it running first. |
| Notes: |
My wife's uncle David bought it new in 1978, and drove it until he stoped driveing a few years ago. He gave it to my wife who gave it to me. It's extreemly straight, paint job is orginal and in very good shape, interior is in excelent shape except for the drives seat and the fake crome trim which is peeling. It's a giant paper weight in my garrage at the moment. |

This is a screenshot of DesktopDyno with all the math entered from my 347. A few things need to be said about this. 1: the compression Ratio is VERY high, im prolly going to have to run race gas or put dished pistons in it (Thick Head gaskets are for...

This is a Photo of one of the exaust ports on the GT40 heads. You can plainly see that it has been Jornal and pocket ported, as well as Polished to a Reflective surface. This is important for exaust ports, dosnt matter for intake.

This is my oldest friend Adam, been friend since the fifth grade. As you can see, he loves his job. Next to him is my 347, undoubtably woundering what he plans to do with that over sized tool.

This is a picture of a HO 5.0 block that has been bored 30 over, What the picture is showing is the notches that I made to permit enough clearance for the piston rods.

Finally ponyed(lol) up the cash to buy new distributor, igntion box and coil. Got em on ebay, distributor and box is Procomp, coil is MSD. All three are NIB and unused. Should be able to get this thing started and broke in now. | 250.00 | | 06/23/10 | Miscellaneous | | Stuck for a little while.
I need a diffrent distributor because the HEI hits on one of the journals and cant be timed in correctly. Saving up for the exaust instalation, hopefully soon with in the next year I'll have this on the road. The toyota is taking prioity at the moment becuase it'll get more than 5mpg. Just a practacality thing. | 0.00 | | 03/09/09 | Repair | | Sooo close yet so far.
Spent the afternoon with my brother finishing things up, everything is plumed in and plugged in except for the battery and ground cable. And other than that, the only thing the prevented us from starting it today was that one of my exhaust pipes didn't fit, my brother is taking it to his tube mandrel and going to have it bent to fit tomorrow, only thing is he wont be back down till the end of the month, not like I'm going to have time to do anything till then anyways. I need to find extra work so I can afford to have a custom exhaust put in this thing.
I did solve the shifter problem by just putting in a shifter cable, though I'm still fighting that to fit right. Having problems figuring out exactly how to mount it to my truck, I might say fuck it and just buy a floor shifter kit for it, but that's more money I don't have at the moment.
Any free time I have I'll spend putting the aesthetic and entertainment accesories on it in anticipation of running it soon. Stereo amps, speakers, gauges, wench, I need to price lift kits as well, I remember finding a few that were reasonable. I need to do the exhaust first though.
There are a few minor repairs I need to do aswell, I still havent done the rear breakes, and both diffs are leaking slightly so I'll put it on my list of things to do, I guess I should prioritize that over the
stereo and stuff.
Last of the lose ends:
*new seals and gaskets for my front and read difs.
*Secure Shifter Cable
*Rear Break Cylinders, Springs and Shoes
*Siphon out old gas
*find a shop to install custom exhaust at a reasonable price, or find a premade kit from LMC or something.
*I seem to be missing one of my signal lights
*Install stereo amps and speakers
*
