Some pics of my 1940 coupe, here in Brazil. 4 wheel disc brakes, Chevrolet Opala independent front suspension, rack and pinion, 3.07:1 Dana 44 rear, Clark four speed trans. It's powered by a 266 (250 bored to 4"), 9,5:1 compression, lump ports, 1,94 intake valves, 1,72 roller rockers, Isky 238°@.050 cam, .525" lift, Holley 600 double pumper. Runs low nines in the 1/8 and should run high 13s, low 14s in the 1/4 mile. Despite having tall gear for drag racing, it's a lot of fun on the street!

I use tube headers, in 6x2 configurartion, with 2,5" pipes and 2 glasspack mufflers. This past weekend, it was dynoed at 231 hp to the wheels. My brother's turbo/EFI 250, 53 Belair was dynoed at 330 rear wheels hp, at 10 psi. How can I atach photos to this forum?

You have to attach them from whatever web host you place your pics on.

Mine, normally aspirated topped 303 lb-ft at 3250 rpm, I think thats impressive, given the relatively hot cam (238° @ .050), 107° LDA, with a pretty "flat" curve from 3.000 to 5.200 rpm max hp. The car really have a crisp throttle response! I don't have my brother's graphic in hands, but it produced a maximum of 397 lb-ft, at an even lower rpm, I believe, since he's using a stock cam, and 10 psi of boost. I think that, a bigger cam can give me more hp, without sacrificing torque, only moving it a bit higuer on the curve, since my car generated around 230 rwhp at ONLY 5.200 rpm (around 270-280 hp at the crank)). Didn't flowed my heads, but I think, given the flow caracteristics, in the neighborhood of 220 cfm (1,94", lumps, unshrouded chambers) more agressive cam shoud be benefical. Guys here in Brazil are churning out 450 plus flywheel hp with webers, and 14:1 on ethanol. TLowe is testing some interesting combos, I saw his 250 on Youtube. My present combo, by the way is very similar to his, but mine, seems to produce a little more torque, in lower rpm, maybe, because my engine is overbored to 4 inches, (266 cu.in.).
