A mild street 383 Small Block Chevy that was intended for a 41 Ford pickup street rod made for pulling a trailer. The goal was Max torque while keeping mild street manners and daily reliability

A standard 010 350 block bore and hone .030 with a torque plate, decked, magniflux’d, and line honed. A balanced SCAT bottom end with KB hypereutectic dished pistons for a pump gas friendly 9/1 compression, 3.75 stroke cast steel crankshaft, 5.7″ connecting rods, and clevite bearings

A factory windage tray, Mellings HV oil pump, and 5 quart oil pan

A pair of Pro Topline Vortec style aftermarket heads design was intended to increase torque which fit this build perfectly. They were pocket ported and had stainless steel Ferrea valves added to ensure good flow numbers

The valve train was a 264/270 Iskenderian Mega camshaft, lifters, valve springs, steel retainers, and clips.  Custom length one piece Comp Cams chrome moly push rods along with self-aligning full roller rockers.

An Edelbrock Vortec Air-Gap RPM Performer intake manifold, Edelbrock 750 Carburetor, and HEI distributor

Bolted up to the dyno a 20 minute break-in period then a few pulls to the optimize timing and jetting we had 380 horsepower @ 4900 RPM and 460 lb-ft torque @ 3400.

The engine had over 400 ft-lb of torque from 2500 to 5000 RPM.  

This 383 has that muscle car sound without being over the top. It will work for any street rod, muscle car.  Pump gas friendly it is mild enough to be a daily driver
