"Pep" for my C2
I am looking for some suggestions for a "factory looking" 300 hp 327 motor to eventually do. I would really like it to look almost exactly like the factory motor down to the ignition shielding, but yield 400ish horsepower. Is this possible? One of the things I thought of was a 400 s.b. stroked to maybe a 422, aluminum heads (painted of course), roller cam, and an aluminum intake painted for the iron look.
The problems I see are the carb that can support a motor like this and look somewhat stock, finding a good intake that looks stock or close to it and has a oil filler tube but could support 400 hp, and of course the ignition. Is this even possible?
Another part of me says make is a BB clone and find a 427 and do the same to it... suggestions?

Thought About A Zz383??
A ZZ383 WITH A pREFORMER VORTEC MANIFOLD WILL GET YOU about 405-410 hp and 450 torque....will fit under the hood and you can run 3.36's with ease in the rear.. can make it look close to stock

As far as the oil filler opening, I'm sure a machine shop could create one in the manifold for you....

You could do it easily with your 327. I would run a small journal 3.75" stroker crank ( they make 'em for the early blocks), a 6.00" rod, a light weight forged piston. If you have the engine internally balanced, you can use a 327 balancer and flywheel/flexplate.
Your 300 horse engine should have a 461 head. These can easily be worked to flow in the 240-250 cfm range (it will require a competent porter, but the flow numbers are attainable). A 67-68 Z/28 intake is a high rsie dual plane, and it has an oil filler tube. An Edelbrock Performer RPM (not air gap) has a pad for an oil tube. Some Performers also have a pad for an oil fill tube, but they don't all have it. They are good intakes, and became much cheaper once the airgap was released. A carter 750 would look reasonably stock on the Edelbrock intake, and shouldn't be too hard to find.
If your car has the 2.00" rams horns, a step-up to the 2 1/2" manifolds will help some. headers, with a good 2 1/2" dual exhaust would help even more. With the above, it wouldn't take too much cam to make 400 horsepower. You could probably make those numbers with a true 10:1 compression and a LT-1 cam.
