Matt Shaff's Engine Shop / The Nostalgic 265 Engine Build
« on: March 30, 2016, 04:01:16 PM »
I know I could build my 350 more or anything bigger but I want to see what I can out of this little engine with a modern cam grind and better parts than an old school build. The engine is a 56 265, .060 over that has been balanced. It has cast dome pistons (still need to cc the pistons), 327 rods. It should be in the 10.5 to 11:1 comp range. It will be a street/strip engine. I am planning on using Comp Cams Extreme 4x4 Hydraulic Roller cam, .474 lift int & exh., duration 230 and 234 @ .050, 111 LSA. Being more limited to 1.94 intake valves due to bore size, I am planning on using a set of 1991 L98 Aluminum Corvette heads, 58cc chambers. WIth all this information put into Comp Cams CamQuest, it seems it should be a strong running engine. Reading one of your other posts here in the Engine Shop, I saw you say many people port their heads too much for smaller cubic inch engines. I always thought that could be the case, glad I read that from somebody with more experience than myself. With stock flow showing 196 cfm @ .500 of lift, I only planned on porting them enough to clean them up and make them even. What ultimate flow numbers do you think would be good to shoot for based on the info. I have given ? Also, I am running a single plain manifold with a 650 dual feed, double pumper for a carb and roller tip rockers. I would appreciate any help from all of the rest of the FED groups expertise !
