my friend bought a 302 that has been stroked to a 377. it has camzilla 290°/290°, 228°/228° @.050, 0.552'/0.552' lift, its running .040 pistons, 9.5:1 compression, a weiand single plan intake ported with a swirl pattern to a 2" tall opening, the heads are iron gt-40 port matched with the intake, 2.02 intake, ? exhaust, a 600cfm edelbrock carb, that has supposidly been tweaked to give 50 more wheel hp?, with a stock ignition system and they expect this engine to run in the 10's in a 2600lbs car, is this possible? he bought this engine from an engine builder who said it was in a mustang before and it ran 8's with a different top end, i find this hard to believe. if it ran in the 8's before, wouldnt it need to be rebuilt? the cam was also just put in.

do u believe this?

you sure they didn`t mean a 347? a 302 block is already real compact and to fit a crank with a stroke of 3.750 to get 377 cubic inches with a standard 4 inch bore would be kind of difficult. I`m not even sure the bottom end of a 302 has the room for the crank throws of a stroke that long.

nope 377, thats y im suspicious. unless its a 351 stroker, are the heads interchangeable froma 302 to a 351, im not a ford guy so my knowledge is limited.

if its a stock block Id say the possibilty its a 377/302 isnt very likely, now if its a 351W definate possibility, and yes the heads will interchage, but youd have to drill the heads to accept the larger windsors head bolts...(if the heads are off a 302) If this thing ran 8's I doubt if its a stock block...guy's on the street with moderate boost are spliting these blocks and Im sure they arent even close to the HP it would take to get into the 8's...

I would want a complete run down of the parts installed and the block used...any casting #'s you can see? and Im here to tell you that imho there is no way you could get a stock headed 302 stroker in the 8's...maybe with a ton of boost and cleavland type heads but still I would be skeptical...HTH 2wld4u

Sounds to me like someone is getting their leg pulled. No offense but are you sure he's not talking about 8's in the eigth mile. I definitely don't believe 8's in the 1/4 and 10's even in a light car without a serious poweradder on that combo is highly unlikely. From the specs you listed it is basically a warmed up street engine. Also modifying a 600 Edelbrock carb for an additional 50 rwhp sounds very fishy to me. Anyhow good luck and have fun!

That thing sure as heck never ran 8's in the quarter. The only way it could go that fast with that engine, is if you drove it off a cliff... and that would only work once!

That 600 CFM Edelbrock would be a major restriction, even on a 350 hp 302.

And by the way, you won't get 377 cubes out of a 302 block.

[Super Chevy]

he definately said 8's in the 1/4 mile, the block isnt stock, but i dont know what exactly has been done to it. ill try to find out. the heads are off of the previous engine that was in the car before which was a 302. this does sound really fishy.

[lluciano77]

Here is a car that really runs 8's.

You can't possibly believe a 302 like the one you are talking about is going to even come close.

Honestly, I would be amazed if that engine broke into the 11's... Really amazed!

We ran mid 8s but it wasn't until we spent near 50 grand,by the way,that included a 1000+ HP stroked alky Hillborn injected BB chev,just something else to compare to.

[Super Chevy]

oh man this is great, but even if i told him what you guys have said, he wouldn't believe me. so sad.

[2wld4u]

its not that I personaly dont believe you, its that you need to know more, a 377 can run 8's, a 302 based 377? I havent heard of anyone doing this, but considering it would be a good high RPM build, big bore short stroke, I just can't see it with a 302 block...now a dart block or any aftermarket block with a 4.125 bore or bigger could make this a possibilty, and it would need some serious R's N/a and this would need a serious head...like a set of blue thunders, heavily ported...so yes its possible and if just one of the variable I mentioned arent up to "spec" meaning aftermarket block and heads I wouldnt think it was legit...just my .02

Give him an easy out,say maybe you meant the 1/8th mile,sounds a little more believable.

[Super Chevy]

well, it doesnt have anything near what you are saying, i think someone gave him a sales pitch, the engine cost him $2200 cnd, i was thinking maybe he got the deal of a lifetime, but when he said it ran 8's i had to start this thread to get your opinions, he doesnt want any of my freinds to know about this engine so he can suprize them when they go to race or something. im sure he still got a good deal and the car is going to be really quick but there is no way that engine ran 8's, even if it did, i wouldn't want it, maybe if it was rebuilt. but with what i know about it, and the specs that i was able to give you, how much hp do u think it has? does anything seem miss-matched?

Its vertually impossible to garner 377 cubes out of a 302, since just to stroke it to a 347 required notching and grinding clearance spots on the bottoms of the cylinders and other places. I am a Ford fanatic, and would love to see such a thing done, but, IT JUST AINT GOING TO HAPPEN. I could believe a 302 turning 8's in the 1/8th mile in a light car (2500 lbs or so), and a very deep gear. I think your friend is blowing smoke up your tail pipe. It is possible for a 302 to get in the very high 12's in the 1/4 with a 600, as that would give the engine all the fuel and air it can use up to 7000 rpm.
As for common stroker kits for the 351, most common are 3.85" and 4" cranks. The 3.85 stroke brings you in at 387 cubes and the 4 inch comes in at 402, this being with stock 4 inch bore.

not the 1/4 MILE! THE 1/4 KILO, THEY'RE IN CANADA!
