RX7 race car project - PDenbigh - 03-15-2007
Someone should get on this. It comes with a roll cage and right now is less than $900. Maybe work a deal for one of the parts cars.

Will a SBC 350 fit in that?

Hrmm. another GRM candidate! I have a 350 that probably needs to be tore down and put back together - but as far as I know the block is good. We could dremel the heads (be good enough for a GRM car right?) - so for the cost of a cam, rings, maybe pistons, and rebuilding the carb, gasket, valve stem seals, and pushrods/rockers, junkyard transmission, and driveshaft...hrmmmm

Something like that would make for a fun project.
I have a feeling it will end up being much more than that though.

try google, many people do what you're looking to do.

FEM-MHP126-000 $259.95 - Standard Bore, Standard main 350 Rebuild kit on summit, this includes new flat-top pistons, rings, rod bearings, main bearings, cam bearings, gaskets, high volume oil pump, freeze plugs, plastigage, assembly lube.
We can get this in a 30 over size too, if we could score some cheap/free machining.
There's a cheaper kit, no pistons, cam bearings, and a few other things - depending on how it looked after tearing down, might could go that route, it's 139$ or something.
the cam-shafts, if we went with summit, we could get a kit with the lifters for as cheap as 70$, or 170$ for a lunati voodoo cam/lifter kit. I am not sure what heads are on it, so I'd have to do some research to see about the max lift, but these cams are usually in the .460/.500 lift range with stock rockers.
Summit Steel Roller Tip Rocker Arms - 89$
Summit True Roller Timing Sets - 31$
not sure what shape the heads are in, might have to buy a rebuild kit for those as well, I can't find out exactly what the heads are without checking the casting numbers - but i'd guess maybe 150$ - 170$ for that? Kits include:
* Valve springs
* Steel retainers
* Valve locks
* Guideplates
* Rocker arm studs
* Valve seals
Not sure what the carb is, i think its an edelbrock, but could be wrong. Anyway, the rebuild kit on that is $36.95 for a performer series carb. I'm not even 100% sure it even needs a rebuild.
Cheapest I could find on a 3Spd Auto Transmission from Summit was like 645$ - So, this is kind of an unknown, because A) I'm sure we can find A transmission in a junkyard, in an unknown state of dis-repair, or buy a rebuild kit which is why I picked a 3spd...cheaper, and easier to rebuild if we went that way.
Further Unknowns: Connecting the transmission to a driveshaft, to a rearend..how do people do this? Buy special yokes? Swap in a GM rearend?..or is that pretty standard across the board? Also - fabricating, or getting made a driveshaft..no idea the costs on that..anyone?
- HAULN-SS - 03-15-2007
Oh yeah - torque converter..i'm assuming would come from a Junkyard car too. If I've forgotten anything, feel free to throw it up. But, yeah - that's getting pretty tight on the budget as is, for that expensive of a roller to start with.
- ViPER1313 - 03-15-2007
Other things it would need:
-fuel tank
-fuel pump
-wiring harness
-all engine accessories
-radiator
-tires
-brakes
etc, etc, etc.
- HAULN-SS - 03-15-2007
Looks like it has tires, probably brakes, and radiator..good enough for pissing around a weekend at a track. Fuel tank, alternator, and PSteering pump, fuel pump all come off a junkyard car, no wiring harness needed, nothing is computer controlled...but shifter/linkage is something I forgot
- CaptainHenreh - 03-15-2007
You'd be way over budget. 800 dollars is alot to spend on a roller for the Challenge. Recouping budget is a big part of the Challenge...that's about the only way you can spend big money on a starter and get away with it.
You're also forgetting that even if we get cheap/free machining cost...we have to count the typical retail cost of that machining in the budget.
Plus, there are way cheaper RX-7's out there, but I think a Chevy is the way to go. Two years running the winner has been a Ford powered FC, I think the Chevy has greater power potential.
