A new cam would be a great mod for you to do. One of the members here has put a LT1 cam in his car and he is really happy with the results from what I rememeber. Another cheap mod is to do a realy good tune up, put a catback exhaust (headers, cat or no cat, muffler) 3" is a good one to put on there. You can put an AFPR on your car, 1.6 Roller Rockers, gears would be a good addition for that car. Suspension mods are a good idea like subframe connectors, strut tower brace, new sway bar do a frontend rebuild bushings and all. That should let you get a good start on that car.

86,

There's a really good chance that you have the Borg Warner 9-bolt rear end. If you decide to change gears, it's gonna cost you plenty. If you swap rear ends, toss the old one my way. I could use a spare bulletproof differential.

The Borg unit is very strong. It makes the stock 10-bolt Saginaw look sad. It rivals the 9" Dana/Eaton (Ford) diff for strength, and in a much smaller package.

The cam is certainly the weakest design you could have. Right after that, the heads (head flows) are not really stellar, either. But the single biggest restriction (is that an oxymoron?) is the plenum just behind the throttle body. If you think the 48mm TB is small, wait until you see what's right behind it n the plenum. Get out the mill or die grinder and start making the plenum lighter.

If you have a high-mileage engine, you might want to consider a roller conversion and reworking the heads for larger valves and deeper bowls. About the best you can do in the small 305 cylinders (without deck machining) with SBC valves is 1.94/1.50. Shrouding is a major problem with 1.94/1.60 valves in the small heads. 1.94/1.50 is a better fit, but the intake shrouding will still occur if you don't do some chanmber modifications, and probably flycut the case deck to clear the valve diameter.

But don't give up there. Far too many people seem to be "married" to the stock SBC valve sizes, and thus stick themselves with few choices. A good alternative is a 1.875/1.550 Buick 350 valve set. You'll force your machinist to use his/her brain a little to select the right cutters and stones, but they fit nicely with no interference and have a longer tip length (allows a longer installed height of the springs to let you use a higher lift).

Port ceilings can be raised quite a bit on the stock castings, and the port radii can be elongated fairly easily. Beyond that is the common volley of parts thrown at the engine, like 1-1/2" headers, better flowing exhaust, AFPR, enlarge intake base - all the bolt-on stuff.

Vader

I don't have my PROM buring equipment yet but what would happen if I put a LT-1 Cam in a 350 with a 19lb injectors and AFPR and 305 PROM? (yeah and the 350 knock sensor too).


????!!???!?!?!?!?!?!?
