For 1970, Corvette buyers could opt for one of three small block 350 CI V-8s—the standard ZQ3 with 300 HP, the L46 with 350 HP or the new LT1 with 370 HP. Fitted with a 4-bolt main, a forged steel crankshaft, impact extruded pistons, a high-lift cam, a low-restriction exhaust, an aluminum intake manifold, a single 4-barrel carburetor, 11:1 compression ratio and finned aluminum valve covers, the LT1 revved quickly and freely and was a breath of fresh air for many enthusiasts. Sadly, it was not available with air conditioning, and while that likely doesn’t account for just 1,287 being built for 1970, some wonder if it accounted for the low production, at least in part. Most agree, though, it was the cost of the engine itself. Finished in Marlboro Maroon with a black interior and a white convertible top, this 1970 Chevrolet Corvette LT1 Convertible is fitted with a matching-numbers 350/370 HP V-8, a 4-speed manual transmission, the original radio and functional fiber optics. Accompanied by the original Protect-O-Plate, original 1970 owner’s manual, original 1970 consumer information booklet, a new vehicle warranty booklet and a partial tank sticker, it also features a color-matched auxiliary hard top. For 1970, Chevrolet unveiled three hot new engines for the Corvette including the 350/370 HP LT1 V-8 and the 454/390 HP LS5 V-8. The third was an absolute racing brute, the 454/460 HP V-8, but it could be ordered if someone wanted it badly enough. That said, the 454/390 LS5 big-block set a customer back $289.65, while the 350/370 LT1 hit their bank account for a whopping $447.60. While the big-block romanced most motoring enthusiasts with brawny grunt, the LT1 delivered a stunning blend of balance and poise for a much more rewarding driving experience. Reduced forward weight bias meant less cornering understeer, and less curb weight equated shorter stopping distances and less fuel consumption.
