so much easier, the 403 is the same outside dimensions as a 350. the steering box will clear, the shift linkage will clear. everything would be way better.

how did the non power rack work out ? was it hard to steer ?

Me and the Mrs. are overdue for an Ellensburg visit.
if you go to rack and pinion steering the bbo will work with room to spare . it is that steering box behind the sub frame that gets in the way . headers on a small block olds barly fit , some you have to massage with a hammer . I did a 74 omega and had the front end was already done with a new steering box so I built a calm 403 w a 200r trans ,fun car I regret using 373 gears the tourq needed 323 or 308. I will be doing a 74 ventura with a 550 hp sbo 433 dx moter th400 and 308 gears ,

From what I've read rack and pinion setups seem to be iffy, probably need to the buy the expensive conversions.

Whatever happened to the O.P. and this project? It sure would be nice to know how things turned out.

I am still here, sorry about not really concluding this thread. I am a very busy person at the moment. The car is 99% complete at this point. I have all new interior, including a headliner from acme auto headlining. I have driven the car to work several times. needs the windshield chrome installed, and an exhaust built, and the subframe connectors installed and other little work, but she is pretty close. My summers are pretty busy, this is the time of year i have more free time to play with cars.

Exhaust built? What happened to the "Jose" exhaust? LOL.
What size are you thinking?

2.5 exhaust I feel would be more than enough. I'm revving the 455 past 6k. I have some small Donaldson mufflers I cut the plug out to make them straight through to just take some of the harshness out of the note. I'm hoping to install a 403 after all this work I've done. I got a block for free and I picked up a set of forged piston nos off of Ebay, I also picked up a 100 dollar 330 for the crankshaft. So I have a nice pile of parts sitting aside
