A good friend has a roller cammed 377 with reworked Canfield alluminum heads just about ready to go in an early 90's S10 extra cab.He hates hydraulic cams so with a solid roller this thing should turn some pretty high RPMs.He does all his own machine work and most of mine. With the lite tail end of the S10 he does not want the torque of the 383 or the 406. Many stock car guys that are not limited to 355 or 358 c.i. prefer the 377 over the 383. For a street car I like the 383 better,for a light drag car I'll take the 377 every time. Personally, for my car weighting 3600-3700lbs Id rather have a long rod 406 than either one. Having said that I may end up with my 355 simply because is a good motor,built well and its already paid for. I can apply what money I have to finishing the car. I am subject to change my mind at anytime even to include my first big block. Having built many, many small blocks maybe I should stick to what I know best.I also have never had a blown motor, sounds interesting , but if my blower education cost as much as my buddy's on this forum I would end up in a soup line somewhere.
