Hi all!
Well, my 225 is getting to needing a rebuild or replacement, so I’m looking for suggestions to get the most bang for the buck. I like my slant six, so prefer to try to make it fast and cool as opposed to swapping it out for a 360. With that being said, I’d like to get a build making a hp per cube, or maybe a bit more, shooting for 225-250 if natural aspiration, over 300 if I go to some kind of boost.
Here is the current setup:
1967 Barracuda convertible
225 with a Clifford 6=8 package (Clifford intake, Edelbrock 500, Clifford cam, split headers, dual exhaust)
Stock 904 transmission, 7.25 rear with 3.91 gears, 235/70r15 tires on the back.
Car is basically an occasional weekend cruiser, but would like to have more fun stoplight to stoplight, and maybe try her on a 1/4 mile once or twice.
I don’t give a damn about mileage, just want it good for street.
I know, I’ll eventually break the rear end with the 7.25, but will cross that bridge when I get there.
I live near Tampa, FL, and so far none of the shops have much interest in trying to build a slant, and the only two that do are only interested in basic rebuilds for around 5k. I’ve never built an engine before, so think it’s probably a bit above my skill level, especially since I got nobody to help me with any of it.
So, thinking of sending it out for lots of head work. Oversized valves, heavier springs, porting, polishing.
Block, I’d like to go to Wiseco flat-tops (maybe .045 overbore?), Molnar rods, and need a really nasty cam.
Prolly keep the existing intake, carb, and exhaust…..but might like to consider someday going to either an Aussie speed blower manifold (Eaton blower, maybe?), or a Torqstorm blower. Would such things be compatible if I build the engine with a higher compression??
Another possibility is a Mabbco rebuilt long block with their “muscle camshaft”, (they don’t give out specs) and flat-top stock size pistons, but they won’t do any overbores.
So, suggestions, please? Stock torque converter ok, or do I need something different for that? Any good shops to talk to for head/engine work? Anyone local want to join in on the fun?
