18RG was homologated im pretty sure. Unless it was the fangled 153 thing.

If anyone can find or knows of the homologation papers that show an rt104 and the 18rg, I would be very grateful.

But in the meantime I have to use the 18r or rc.

RT104 im not sure about, but i would think that the RA45, and RA23/28 Group A papers would show the 18R-G

The rest of the post still stands though, a 4.7 will make your 18R-C worse due to the lack of revs. My RA40 has longer drive ratios than my RA28, both have stock 18R-Cs which are running reasonably, though the RA28 has extractors. The RA28's motor is a bit fresher but suffers because it runs out of puff too quick, so acceleration off the mark is quicker in the RA40... right the way up to 100.

Cam and major head work will go a long way to fixing that though. Then the weber carbies will help.
