GT to Cobra

[Mustang92]

Okay let's clear up some confusion here. For starters yes you can put 4v heads on a 2v block. There is some modifications that have to be done but not impossible. As for why would you want 4v's if you hadn't noticed there are 11 second bolt-on Cobras out there no 2V has done it and never will with just bolt-ons.

You'll need more than heads and intake to make a 4v motor. 4V motors rev to 7K RPM all day long and a stock 2v rotating assembly will not handle that. Plus you will lose compression with the stock 2v pistons and 4v heads.

Roughly speaking you'll need: heads, intake, inlet tube, 24lb injectors, MAF, pistons, crank, timing chains, timing chain covers, radiator crossover tube, radiator hose, EEC recalibrated, alternator, accessory brackets, exhaust manifolds...
