My swap was easy and cheap,
I used 2.5 in square tube welded into a solid box with a tube throught the center for the bolt to mount.. 69 GMC truck mounts with the center bolt that passes through. Grade 9 bolts and safety cables on the left side Added a 3/4 in plate steel spacer to get oil pan off suspension. This mounted on the original perches with perch holes slotted back and offset 3/4in to align motor and tranny with pinion, meant I had to remove hoodlatch but left room to clear HEI distributor. Then I took an old turbo 350 short tail shaft with tranny mount, lined it up so all was level and offset 3/4 inch to align with rear carrier, and built a spring steel tranny crossmember out of a collapsed(flat) leaf spring bolted through the floor at the frame rails. That gave me just enough clearance to use $89 shorty center dump headers and clear the crossmember. 6 of 8 cylinders are behind the shock towers. I used the short early vette water pump, a one wire hookup GM 100 amp alternator and an 89 S10 4.3 V6 with air and towing package radiator fitted by trimming the frame rails at the core support just a tad and mounted with the original GM hold down and rubbers.I use a 14 inch slimfit electric fan wired to run continuously, and a 160 thermostat. I run a 355 with double hump heads 10-1 compression, 512 lift Lunati cam , a 3000 stall throught a turbo 350 with a quicksilver shifter. Manual steering that steers great, heat works, all accessories work, thanks to a universal speedo cable with the Jap end braded on the top and US on the other with a camaro gear in the tranny it is only 2 mph off at 75mph. I have an r180 limited slip rear (which makes me nervous, I hope to upgrade). I live in the south and can sit in 90 degree traffic all day and never go over 200 degrees and stay around 165-175 degrees on the move. I have driven this car 12,000 miles and raced several weekends in the last 2 yrs with no problems other than some dash wiring thanks to 30+ yr old harness. I don't "flash" the converter so the rear is holding up and I run 93 octane gas with av gas mix or race gas at the track. I have used 89 and additive when I'm just riding around but i keep the timing back a touch. ( Makes for a nice bangin' idle too in gear!!!) Some might consider it a junkyard dog but it is faithful and LO' Buck!
