Thread: chevy 307?

Tweet

i was just wondering...ive never heard of a 69 nova 307. does anyone know anything about this car? is it rare? whats it worth? anything you know would be helpful.
thank you

I owned one. Bought it new, bright yellow, 3 speed on the column, and a 307 2bl with a wopping 200 hp. Or so it claimed on the airbreather. Power nothing, all the engine had was an alto, One fan belt. $1700. out the door. I litterly beat the living crap out of that car. Overhauled the engine twice, a couple of dozen clutches, and several rear shock mounts. I added a 4bl and headers, It would melt a set of L60's into the pavement, but it was dead after first gear. I have no idea how rare they are, the chevy dealer I bought this from sold a bunch of them. It was cheap even for that time.

hey thanks for the info man...kinda helpful.
anyone else i still need to know whatefer you can gather for me. the reason why is i just bought a 69 nova and it says 307 on the side but i havent got it yet and i want to know if it was worth it shit like that.
thanks

The 307 was a 283 block with a 327 crank, 3.875" x 3.250"

u can get a stroker kit for a 305 to make it 335 if u need that kind of info im sure it'd work on a 307 to

um...no...that kit doesnt work with a 307

Maybe you could bore it 0.030" and use a Scat 3.750" crank. That would make a 359 long stroke motor.

Hey man that 307 does have the same crank as a 327. Good power potitonal. the 327 set up the same way as a 350 will smoke it everytime. I would bore it .040, use a set of gapless rings, if your heads are 58cc use them but put a bigger valve set in with a 3 angle valve job and have the heads ported and polished. Get you a nice cam with about a .490 lift, if you go over .500" lift you need to change the springs. There is lots of good intakes you can use. I like the Aluminum Air Gap from eldbrock. Holley 4 Barrel. I am a Big fan of the Mallory Unilite Distributor. Use some 8.8mm plug wires and I like the Bosh Platinum +4 Plugs. Shorty Headers with dual 2-1/2" pipe and 40 Series Flowmasters.

Have fun,

O yea you will probally need a tire fund, you should be ripping the tires off with this set up.

awesome guys thanks alot
ill be sure to talk this one over with my buddy. we are going down to get it this weekend hopefuly, it is in iowa and we are in mn but we really want it now! i mean cum on now its a 69 nova(which arent that bad in my book) for 200 bucks
damn you know your shit chicken and that sounds like a pretty bitchin setup.
thanks for the input fellas

standard autolite 86's work good to and they arent 6 bucks a piece tehehehehe

i think i agree with that one :-p
lol

Some 307's can be punched to 4" bore and use stock 327 pistons. Check for core shift before spending any money, though.

Most 307s can be bored to 4 inches and You can make it a 350 ci. using a 350 crank and std.bore 350 pistons. I know of at least 5 that have been done that way. The only problem with that is if down the road it ever needs to be rebuilt again, you can not bore it any further. If you want a good performance street engine and You want to used the original block--Go for it. If you want a race engine, I wouldn't do that.

Hey riverhorse59, a 327 will beat a 350 everytime. Who ever put a 350 crank in a 327 messed up.

As much as I loved the 327s and still do, I do not agree with your statement at all. Why do you think Chevy graduated from the 327 to the 350 in 1969 and never looked back. Let me give you this example.

65 to 68 Corvette,327--350hp. 69 Corvette,350--350hp.

350 hp. @ 5800 RPMs 350 hp. @5600 RPMs

Torque 360 @ 3600 RPMs Torque 380 @ 3200 RPMs

Both motors had 11 to 1 compression

Years ago when I was debating on weather I should build a 383 or a 406 I went to a friend who has been building race motors professionally for both Nascar and for the drag racers for over 30 years. I ask this same question. His answer was , A 327 and a 350 built exactly the same and with the same care, the 350 will be faster. A 383 and a 406, the answer would still be the same.

We've all heard it a 1000 times before. There is no replacement--------
