Would a 403 achieve a similar goal and still look like the 307, protecting the 'authenticity' of the Hurst cachet?
IF the 307 is in good running condition, I'd pull it and keep it on a stand, maybe purdy it up if you ever want to sell the car. Olds 350s are brutal when built right, even mildly.
I purchased my 84 H/O with a stock 403 installed. The 307 had long since departed this world. Victim of a dropped valve. I'm leaning toward pulling the 403 from my wagon, freshening it up (oil leaks everywhere) with a cam change, and popping it in the H/O. It has ported, big valve #5 heads and a Performer RPM intake. Really motivates that 4200 lb wagon.
The 307 and 403 were both rated for the same HP, but the 403 was rated with I thing 50% more torque.

so what would and edolbrock performer carb and and edolbrock intake manifold do to the horsepower
They would obviously be an improvement over stock. If it's got the OEM carb on it, it's most likely computer controlled. Keep it around, those in working condition are worth some serious dough to the right guy. I'd say maybe 20-30hp gain. Not to familiar with how 307s work with mods. I always chucked 'em.
mr sony so ur saying that what would u put in there then instead of the 307 i know that people rather have the bigger engine i kinda building a show i want the engine to be big but not a drag car you know what i mean its hard to explain i just have been turned in many directions and dont know what to do
