Greetings small block experts! I've been out of the engine building game for 20 years or so and I'm sure things have changed. I'm in need some expert guidance from the savey sbc folks here. I'm in the process of building a street engine for a '55 Bel Air. It will be a .030 over 350 4 bolt block with 041 64cc heads with 1.94/1.50 valves. Stock crankshaft and connecting rods. The car's curb weight will be 3160 as nearly as I can estimate. I plan to use a Turbo 350 with a stock converter and 3.37:1 rear end ratio. I would like to use a Q-jet since I have a good one on hand. The car will have A/C but will NOT have power steering or power brakes. I want to put together a very responsive off idle to say 5000 rpm engine that runs on pump gas for stop light stuff and cruising. I am more interested in low end performance than a lopey idle. Gas mileage is not a serious concern, but naturally a consideration. What would you recommend in the way of pistons, intake, flat tappet cam, valve springs, ignition and carburation? Many thanks in advance for your advice and recommendations.
