Hey All,
I no longer have my '69 GTO, but thankfully it's in the hands of someone with the time and resources to take it to the level it deserves.
What I *DO* have is the 283 from my '64 impala (the later I no longer have), which I am preparing to replace the 4.3 V-6 in my '97 S-10 2wd. I've gotten some good information about the swap itself (not an original idea at all =) ) from the s-10 forums, however what I need is some input on how the engine should be set-up to run optimally in the S-10. The engine ran very well in my '64, despite the cars size, even with the factory Powerglide and standard rearend, ratio unknown.
I rebuilt it myself back in '92 and here's the details of what it had:
-bored .030, cast flat top (4 brow pistons). Bore = 3.905"
-.010/.010 (3" stroke) steel crank, factory rods/bolts.
- rebuilt (but not planed) 60cc power pack heads with factory 1.72/1.5 valves (it was originally a 195hp/2-bbl engine, but I guess the put PP heads on everything by '64).
- edelbrock performer cam (204/214 @ .050 lift 0.420 int./0.442 exh)/matching, roller time chain.
-edelbrock performer intake, quadrajet off of a '70's 350/untouched
-stock point distributor with Moroso wires and MSD blaster 2 coil.
It's not been run since fall of '94 and only had 4K miles on it, but it's been in storage since it was removed and I'm preparing a plan to convert the top end to vortec from a 305 (Heads/intake/TB/injector/ignition, ect) in preparation for the swap since I want to preserve the fuel injection. The 305 vortec heads are much better flowers than the power pack, + they have hardened seats and 1.84/1.5 valves, and more efficient 56cc chamber.
Despite this being a Pontiac forum, I am hoping that some of the members on here have some old school experience with 283's, what worked, what didn't, and their thoughts.
Is the vortec top end a good plan?
The S-10's an auto (4L60) with a 3:08 rear if that helps.
Thanks and yes, I am doing what I can to keep the Pontiac brand alive with my '09 G8 GT, although it's heart is standard GM, LS-engine fare.
Thanks in advance everyone!
