Those intakes can be reversed. Doesn't really matter anyway........same engine underneath it, unless someone's done some swapping with it.
Or, if you'd just notice the 5.0 sticker like everyone else, then you wouldn't have to look at the intake... because 5.0 equals 302. Also, he doesn't have a Boss motor, so the point your making is irrevelant. We are talking standard 302 motors here.
Yes, but fortunately, I don't take things at face value. BradleyGT and Baddad457 confirmed that the 302 upper intake won't fit on a 351 lower, which is fine; that settles it for me. You said that putting a "bigger head" on a small engine won't make more power, which is completely untrue. The point I was making is the one that you completely missed. I never implied that he had a boss 302. I was referring to the engines made in 1969 and 1970, the Boss 302, which had 2.23" and 2.19" intake valves, respectively. My point was simply that the ports were HUGE and they made VERY good power (the trans am boss 302 made an estimated 470hp). Same with 351C heads...Let's start a new thread if you want to take this discussion any further.
I was working with what information he provided, so as not to cause confusion and bringing in information that was irrevelant to his situation. Considering the OP didn't know what motor he had at all, I answered in simple matter, and suggested that a 351 head would not be a better choice for his application. I seen no point into getting into motors that weren't brought up. Have a nice day
That's because you COMPLETELY lost the argument you started in stating putting bigger heads on a smaller motor made no power.
No, my point was valid, and I didn't start an arguement. I stated that putting the bigger chambered 351 heads on a otherwise stock 302 will not help anything out. It's the truth, and you know it.
this is what you posted that started the ball rolling. You said nothing about bigger chambered heads here.
Exactly... putting a head from a 351 onto a 302 would NOT help. Using the "I don't know anything, but I think a bigger number means more power" doesn't matter. Same for kids saying they put a 350 head on a 305.. or the "I got 351 heads on my 302" When in fact in an otherwise stock motor, it doesn't help anything. Just like kids putting a 4 to 2 barrell adapter on top of a 2 barrel intake, and thinking they got a hot rod now. In reality, it isn't helping anything, other than the "bragging rights" of having a 4 barrell. Same for the 351 head on a 302, the 350 heads on a 305, etc. It didn't help anything, no matter what your buddies told you.. Like I said, I was trying to keep it simple, since the OP didn't even know that a 5.0 = a 302. So why confuse them with other motors, when they wanted to know about a 302, and would a 351 head help out on THAT motor.
There, learn to read the entire thread. I said I wasn't sure of the year, 2 posts later. I wasn't sure of the year, and was informed by Mavman72. So, that was the end of the discussion, until some of you had to just pick up the ball and run, when it could have been dropped right then and there Have a happy Thanksgiving, I'm off to my in-laws. I don't have time to stay here and argue with somebody I don't know about something that's trivial
It depends on which 351W heads you use though. Using the 69-74 heads, or the later 351 heads off a lightning (GT40's) your statement doesn't hold water. Which are those heads with bigger ports and valves. You made a blanket statement there, that was a mistake.
Yes, I should have clarified. I forget about the GT40 heads, as I've never used them, nor considered them honestly. I was thinking old school stuff. Have a good thanksgiving, im out of here
Thanks guys for your help and comments. I checked and sure enough, I found the "S" outside the valve cover, which means I've got the "crappy" E6SE heads. With this in mind, is this engine worth while to rebuild, or should I just start looking for another one? With this engine, what are my options, and what could I expect as far as HP? Thanks again for all your help! Art
you can use that one id get some e7 heads a ho cam and rock that bi__h:bananaman it will make good power aluminum intake 600cfm carb headers are must haves brad
That engine may be like the one I just had redone. I bought one with the '86 near flat top pistons and E6 heads. I replaced the heads with $50 E7s with some mild porting. I like the '86 pistons because the have a zero compression height and almost no dish. I'm hoping for about 240 HP with 600 Holley, Edelbrock Performer intake, ported E7 heads, headers and 2.25" duals. If you're looking for something in that range, and that engine doesn't need a rebore, you might get there pretty cheap. If you go that way be sure to check the valve to piston clearance. Mine is a little tight but I expect it'll be OK.
you can run a 1.7 rocker with a stock ho cam and have no problems with piston to valve clearance brad
