Engine build advice

I just posted this in the "performance section" as well-

Hey guy's I'm looking for a little advice on building an engine for my '67. Currently, the car has a smallblock that I know little about. Big cam, 462 casting number heads. Whole lot of bark, not a whole lot of bite. The block decodes as a 283 from 1961. I know-big time. It runs pretty well, Probably in the 250-275 hp range (the same as my Maxima-dammit). I doubt near 300. It's really a mystery of parts. OLD Offy intake, but a new Holley 750DP-which is obviously too much for the car-but it runs well. Carb was put on by the previous owner, who also did the tranny.

I want to be able to cruise with little drama with the wife and 2 kids, run on pump (premium), support A/C (which the car has), and run a high 12-low 13 quarter. A little cam lope never hurt anybody -I'm coming from the world of turbo Porsche (944) which sound like a sewing machine-even over 400hp.

Right now, the car does everything but the quarter time. So, what do I build/buy? 350, 383, 406? What hp level would be needed there? The car currently has a TH350, newly built with a 3000 stall, 3.73 rear.

I owned a 1970 Chevelle SS, which was set-up with a pretty stout 427. Big cam, huge compression, and a lot of headaches. This car will get driven to my office a couple of times a month, cruise on the weekends-and may get taken to the drags once a summer. I suppose I could leave it alone-and just never race anybody. It could pass as a 12 sec car, as long as I never race it, but what's the fun in that?

Do I keep the heads, or sell the motor as whole/running? I don't know if they are 1.94, or 2.02 heads. What would you do?

Re: Engine build advice

Well, your choices are limited only by your budget. But you have set a few parameters which limit some choices. You're looking for a driver, so that rules out tunnel rams and wild cams. So you basically want a strong, streetable engine with gobs of power. Hmmmm, that sounds like the same objectives as about 99% of us, LOL.

Personally, I'm a huge fan of the old adage, "there's no replacement for displacement". I guess that means I'd build a moderate (read: driveable) 406 rather than a wild 350. All things being equal, more displacement will virtually always give you more torque. More torque equals more low-end acceleration, which is what works on the street and makes the car fun to drive.

Lots of different opinions on this subject, for sure. But my vote is: go big on displacement but keep it reasonable as far as cam selection, carb, etc.

Just my $.02

good luck......................
