putting a reman 95-96 roller cam 351-w , w/reman stock ford gt cast iron cyl heads , and stock style dished 351-w pistons into my 2-door 87 crown vic and would like to know the stock compression ratio of these engines

I know the block was bored and fitted with new stock style pistons ,.030 over I don't know for sure , and heads and deck were most likely shaved
cam is going to be ford e-303 roller .498 lift I&e just looking for more power & tq than the stock 5.0 and still be a daily driver

 

8.8:1 with heads that have 64cc chambers.

That won't be a problem.. you'll have at least double the HP of the old 5.0 and a whole bunch more torque but I hope you're using a carb because this combo isn't compatible with any stock EFI system.

 

covnerted original efi 5.0 in ltd to mass air when installing 303 cam used computer out of 90 mustang had to add 3 wire kit for mass air and reroute injector wires to change fire order to 1-3-7-2-6-5-4-8 , also had to reroute wires for smog valves they are different pin location used ford racing19lb injectors going with a edelbrock efi intake for the 351-w , they do recommend 70 mm tb stock 5.o mustang is 65 mm

a word to the wise anyone going to convert non mass air efi to mass air disconnect the cruise like the instructions tell you to I didn't follow the advice and every time I started engine to see it all work it would go into wot spent a lot of time making sure very wire at the 60 pin connector was were it should be , also ckd every sensor cross ref between 87 crown vic and 90 mustang were the same the only different part no.s are the iac valve and air charge temp sensor ,map hose must be unplugged needs atmosphere pressure not manifold ,and 19lb injectors vers 14lb on the ltd you also need a mass air computer ,the plug and comp are same shape just missing 3 pins for mass air on non efi versions

 

coo1 I was hoping for about 9-1 to run on pump gas with the heads shaved , and block decked during reman maybe 9-5 this compression ratio and a cam wakes up the demons in any ford v-8 I ever owned, also plan on keeping efi with the aftermarket edelbrock 351-w manifold , tried to gt a lightning one on e-bay but them jokers want 500 for just the top piece ,those gt-40 tubular uppers look real cool but their not made out of gold they have the round port lower piece too but guys want way too much for used

 

Yeah you can get a complete Typhoon EFI intake which is an Edelbrock copy for $500 and even a new Edelbrock is less than what they want for an authentic tubular GT40 pair. But ya know.. value is all about what people will pay for something.. not about what it's really worth.

P.S. There are much better cam options than those archaic alphabet cams too.. like one of Comps XE grinds for example.

 

SD maybe, but the alphabet cams work all day long with the MAF computers.

I agree, especially with the E cam. LOTS of better cams.

 

those cams are designed and tested by ford racing ,I don't see any problem with them

 

Yes but that was 30 years ago.

 

you guys on these sites like to drum up drama, how a compression ratio question turns into what kind of cam a person should buy, sounds like the crapdashiens drama
sure you don't drive a 78 chevy 350 1500 4wd w/ rebel flag and gunrack in back window ,coors cans rolling all around bed , song on radio about your john deer stuck in field,hen aint layin any eggs, wife ran off with cuz, slim- who cares what kind of grind a guy chooses ,that's like me telling you what ****ree to live in or what kind of beer to drink or toilet paper to use ebz

 

no carb they went extinct 30 yrs ago found a fossil of one in my backyard

 

There's no reason the belittle them, you ask a question they answered they gave a suggestion about possibly better cam that might even give more hp and torg. To ridicule them for it was uncalled for.

 

That seems to be the new norm here. New guy comes for advice, gets some, doesn't like it and then decides to belittle those that chose to help.

 

To the OP , theres nothing wrong with the E 303 cam , you might think about using 1.7 roller rockers with it to give it a little more lift , i used this set up in my truck and it worked great....

 

Lol. "You guys" come on these sites to ask questions that can be answered by google in a fraction of the time it took you to start a thread and wait for answers (not to mention build an account in order to do so). You get polite, "no noobashing" answers to "google questions", with the addition of a little advice from some experienced gentlemen who willingly and happily answer the same moronic questions over and over.

I guess you better get your 3 brain cells swimmin in the same direction and learn to use google, and be happy with your slow setup, if you don't like it here.

Or, learn to measure CC and calculate CR.

 

that's how I found this site googled how much comp does a stock 95 efi 351-w have and search led me to another guy with same question , the answers he got ended up being two guys beating him up over what volume cc heads he had bought, seems like the norm here beat someone up cuz they didn't buy a part you liked better , I think you answered my question how much compression does a stock lightning 351-w have , answerer get a cam with 512 lift , ill keep the 1;6 roller rockers buy a z cam for the 351, save the e cam for the ho 5.0, that's the compression ratio
