well go get a heavy field .and a heavy duty bendix drive.with a iron nose. i used this type of stock GM starter to turn over a 548 14.8 bbc engine . gear starter just take up less room that about it with the cheapy ones . the alum block on the gear drive starter some times need to be milled to get the air gap right on the fly wheel to bendix. i had to mill more then one to get it to work
