This new stroker rod set from Lunati® provides generous cam and block clearance without compromising rod strength.
The connecting rods of Chevrolet’s 383 stroker engines are notorious for making contact with the camshaft or block. Lunati’s new 6.000″ rod set features relocated cap bolts for increased block clearance and a rod redesigned to clear the biggest of cam lobes. High-strength ARP-2000 7/16″ bolts allow maximum clearance with a standard base circle cam, while Lunati’s H-beam design offers unbeatable strength. Developed exclusively for 383 strokers with 3.750″ stroke crankshafts, this Lunati Stroker Rod Sets comes properly sized and ready for installation. It offers the most clearance in the industry at an attractive, cost-effective price

So what block do they fit into and can you convert a 350 block or does it has to be a bigger block?
Hi, Keith. Great question, the 383 stroker small block is assembled by basically using the 350-cubic inch Chevy small block engine block and combining that with the rods and crankshaft from a Chevy 400-cubic inch small block. Essentially giving the 350 engine a longer stroke and changing the displacement to 383-cubic inches.
Depending upon the crankshaft used, you may also have to use a 400ci Chevy harmonic balancer and flexplate/flywheel. The stock Chevy 400ci crankshaft is externally balanced while some aftermarket 383 conversion crankshafts are internally balanced and can be used with the 350ci Chevy harmonic balancer and flexplate/flywheel.
Cost
Hi, Jaime. Most of my sources list between $550-$600/set.
