I am about ready to start spending for my new engine. 351c .20 over 12.5-1 comp. I am looking for any tips that may help. I am using 2v heads for now and can`t run any roller stuff. Intake is stock and am limited to a 2bbl. I am going to use oil restictors and have everything balanced. Rpm should be 7000. Any help will be appreciated, thanks.

You might want to check into a 347 or a 392 there both lighter and can be built for reasonable amount of greenbacks.

I ran a 351c for about 3 years back in stock car days befor are track had mods. First if i remember DO NOT use the restrictors i ended up eating gears off the dist about every other week...we did fix it by drilling a small hole in the plug that is in the block behind the dist(maybe 1/8) The one thing that we also did was run a oil line from the back of the block down to feed the crank...if i remember it went in down by the fuel pump but its been a while, i do know it went right to a oil passage for the bottom end. The motor we had was 12.5 to 1 fully ported heads with 4v valves turned down to a 2.08 for the 2 v heads it made tons of hp... im sure there are some guys on here that could help more or shoot holes it what i have said...those are just things we did to make it live!

I think the oil restricters you are talking about are the ones that lube the cam bearings. The ford motorsport oil restricter kit does not recomend restricting the oil on the front cam bearing. On 302 and 351w blocks you can also restrict the oil before it goes to the lifters and the top of the engine. You can not do this on a 351c because the crank gets its oil from the right side lifter passage. The 351w has an extra oil passage the feeds the crank first and then goes to both lifter banks. You can restrict the oil on the 351c by sleeving the lifter bores. The sleeves then have a very small hole to let oil get to the top. This must be done by someone who knows what they are doing. If the lifter bores are not true you can have cam and lifter problems. Some people run an oil line from the oil passage by the fuel pump (close to the oil pump) to the oil passage behind the intake (last to get oil). I had good luck hooking up an oil accumulator to the back passage.

Hrspwr, since u haven't said what the application for this engine will be, I can only tell u about my experienc. I am running dirt track in a 71 Torino, with a 2V/4V Cleveland motor. 4V intake and carb w/ 2V heads. have a Hi-vol oil pump and w/ no changes to the oiling system, am pushin 80lbs of pressure at 5,000 rpm. this reading is generated at the rear port behind the intake, which is also the last spot to get oil. Need more help, PM me.
