Well got it fired yesturday but this is how it went Just got the 351w in and finally yesturday i went to fire it off. Well after finding a bad ignition module it fired up.But it got hot i put a 160 stat in it but the temp gage went 1/2 way up and stayed, even with my fan on the whole time. So i heald it at the 2000 RPM for 20 minutes. Then it really started getting hot! so i took it up to 2500 3000 and was bringing it back down to 1000 and it over heated!? WTF? then i look around cause i smelled fuel? go to the back and the freakin exhust melted threw the rubber fuel lines that come off the tank! WTF man any ideas why it was running so hot?When i had my 302 in the car i thought? it had a 160 t stat in it also,i could drive it around (as long as i was moving) with it being 90* outside and not turn my fan on once and the temp always stayed right at the 2nd line off cold. peace

I had the same problem on my coupe after putting new aluminum heads on it, its probably an air lock somewhere, just take the radiator cap off while its running and this should get rid of it!

been driving the car as much as i can,but tough when all i get is raniny days:mad: but i have about 300 miles on it and alls good! at first it was a dog from hell went to my buddies house put a light on it and was at 10- (i think?) so we set it to 10+ and what a wake up it did! I would say i'm at about 325-350ish at the wheels? In 3rd gear rollin on the throttle it breaks loose and goes sideways so it's way over my 302 that made 301HP/338TQ at the wheels and it wouldnt do that.I have a "start up" tune on it now and the guy that did the tune will be doing my final tune. That should be done the week of the 19th of april gonna trailer it up to seattle.All i did was give him my specs and he burnt the tune that i have now and sent me the chip back!peace

Wow i'm getting a late start to this thread...but instead of flaming i'll just add that yes that is a fuel pump eccentric, period, dot, the end. Has nothing to do with balancing a cam whatsoever. I have the eccentric from my stock '85 302 on a 347 with an aftermarket cam right now...it has nothing to do with cam balance. If you look there are 2 "cups". The two act together as a bearing when oil gets between them. The reason it's offset is because it spins around and pushes down on the fuel pump arm and that's how you get the mechanical pumping action...just like a tiny floor jack inside your engine.

Really though, some of you guys are kinda a-holes..lol..you should teach, not flame.

looks great!!!

quick question for you , would a 351 clear a heat extractor hood? it has 1.5 inches more clearance?

thanks

i used vert mounts on mine with a eddy performer rpm and if i had one more inch i would have made it with a stock hood. if you can get the height measurements from the TF and the rpm intake you shoud be able to do the math and find out. just a thought.

Very nice work! Can't wait to see the dyno numbers. What kind of compression are you running? I'm having my 408 dyno'd on April 30. It only has 8.8:1 compression though, I was gonna blow it or turbo it but now that the economy has gone to crap I'm scared to spend that kind of cash. Hope all goes well and she puts up sweet numbers for you.

You and me both! But unfortunitly thats all i can get cause the compression is so low. I started another thread of how bummed i am,from the sounds of it my cam is to small as well. So it's time for a bigger cam! peace

I made the compression mistake with a 347 before, and still made 340RWHP with 8.5:1 a bigger cam, better heads and intake. I piston swap can give you 30+% hp at 10.5:1 and valve reliefs for a bigger cam. Don't worry about it, building is part of the fun right. If you have everything else done, these upgrades don't take near the time or money that have gone in so far.
