V-8 Series conversions are extremly popular.I've divided the swap into sections:
Exhaust, Transmission, Motor Mounts,
Radiator and Other. All parts are from Summit Racing uness noted.
Exhaust
Headers for this swap are available from
Hedman Hedders. The Hedman Headers are available in shorty and full length.
The shorty headers cost around $95 and the full length header costs about
$250. All of them can be ordered online through Summit Racing. Hedman Shorty
PN: HED-69520, Hedman Full Length PN: HED-69490. There is no dual exhaust
made as far as I know, you will have to have one fabricated by your local
muffler shop.
Transmission
For a the Transmission I would seriosly
advise you to upgrade to either a TH350, 700R4 or Borg Warner T-5 and maybe the 5-speed that GM put in full size trucks. The
700R4 or T-5 should be swapped out of a 3rd-Gen Camaro. The stock transmissions
just wont live long behind a healthy Small Block. But if you want the stock
transmission can be reused with modifications. If you are trying do this
swap cheaply go with the TH350. You might need some crossmember modifications
for any of these swaps.
Motor Mounts
Motor Mounts are available from TD Performance
Products. One style mounts right to the 2.8l mount pads and are recommended
for use with the Hedman shorty hedders. The other style requires Chevy
mount pads and shells and are recommended for use with the Hedman full
length header. I have been told that they suck because you have to chope up the rad support but I dont know of any other options(other than custom made) Both can be ordered online through Summit Racing for around
$60. TD Motor Mounts(for shorty hedders) PN: TRD-9926, TD Motor Mounts(for
full length hedders PN:TRD-4689
Radiator
The stock radiator just wont cut it.
Try Locating A 4.3L HD radiator or a radiator from a 2nd Generation F-Body(Camaro & Firebird)before getting your old radiator improved or getting a really expensive one from the aftermarket.
Other
Even though there is ton of good V-8
Conversion Tech here I would still buy the "Chevrolet S-Truck V-8 Conversion
Manual" from Summit racing. It is around $30. Chevrolet S-Truck Conversion
Manual PN: JTR-S10.
