port injection cam?

[fe66comet]

I am gearing up for when I get my intake adaptor to run my Ford injection intake. I currently have a carbureted cam in the engine and I am having comp cams grind up a new one. I am thinking of something like this, spec. wise, what do you guys think? I am going with a roller cam so rpm is in the 2000- 6500 range. COMP Cams 35-775-8 thanks guys Jon

What is your current cam and can you adjust injector timing?

I run more cam than that and less lobe sep and it idles nice, no bad behavior.  That's not a bad cam for a cruiser, but it'll be pretty mellow

One I have now is 594/598,287/293 112 separation. I haven't ran it yet so I have no base line but the separation seems to be the difference mostly. The cam I need is for a 445 with moderate ports, stage 3 port and combustion work from Barry. I am going with a Box R trick flow intake that has about 300 cfm untouched per runner. I could go with a little more lift say .625/ 625 but I do not want to push piston clearances too much.

That cam you have is fine for EFI, 112 is already spread, especially at that duration.  EFI can generally handle quite a bit more overlap than that

For example, mine is 286/292 110, for 69 degrees overlap

Your current cam is 66 degrees overlap. 

I sure wouldn't spend any money, that cam will run strong, overlap is king for mid range WOT power and as long as you don't go too tight and give the O2 sensor odd data, it'll love the tighter spread

Cool I'll give it a try, I have to still send the heads off for the final port work and chamber shaping. But at least I can button up the bottom end Thanks .....Jon
