Thanks for the input everyone. I think I'm going to build the 307 even tho everyone seems to hate them. This will be my first engine build I'm going to use the Edelbrock intake, Holley carb, and HEI distibutor with the 305 heads I already have. Any suggestions on a cam?

"Everyone seems to hate them"? I don't think you'll get that here. The only thing about the 307 is it's small. But other than that it can be a nice engine. I'd rather have a 307 than a 305 any day.

If I had a 307 I'd bolt on a set of L30 305 Vortec heads. Need an intake, SA rockers, center bolt valve covers. The payoff is a real good flowing head w/a chamber size smaller than a 350 head. Some info and photos of the L30 5.0d L Vortec head can be seen at NastyZ28.com Vortec Cylinder Heads: The Definitive Guide, post 478.

I don't know about many other places but ill take a 307 any day and twice on sunday. so its not a 350, so what, why is it the common practice is if you don't know throw a 350 in it. why not 283 or 400 be original.

start small work your way up.

for you cam, you'll have about a 800 rpm difference than advertised, so look at your application then go from there

You cannot intelligently choose a camshaft for a motor until you have nailed down the static compression ratio.

Im a big fan of 283s and 307s for cruiser cars; you can use a fairly mild cam and it'll really wake them up, besides people will usually give you stuff for them on the cheap. I even had one nice lady give me $5 and a glass of juice for getting rid of some rusty junk someone hoarded in her shed. Thank you kindly ma'am for your rusty 350 smogger parts that I parlayed into a running 307 2bbl. Add stock 305 heads, Performer intake and a 600cfm Edelbrock with a Wolverine(?) '250H' hydraulic cam (not a roller cam). This is NOT the right way to do it; but my friends vega wagon needed a motor so we could go to spring break LOL. It probably made 220 honest HP (which is different than internet HP), but it ran like a champ, and it was loud and knocked down some decent economy when you drove sensible (Did I mention we were 21 and going to spring break??). Im sure if we had payed attention to detail, it would have done much better.

You have the time and the will to do this correctly. Use the right parts, with attention to detail and it will serve you well. Remember that a 307 uses a little different mindset in terms of parts (Most chevy aftermarket parts are based on the 350ci smallblock) so you'll want to avoid the popular Performer RPM manifold and 650cfm carburetor. You can't use a 2.02/1.60 set of valves in the heads either

Use a quality rebuild kit (Northern seems to make one); you probably want to make sure it has moly rings, a roller timing chain set and either King or Clevite bearings. Camshaft is dependent on your compression ratio, but it'll be fairly mild compared to the 350 crowd.

Ask lots of questions and HAVE FUN

350 block into a 327

I agree with the k.i.s.s. method. If you're on a budget and money is an issue, maybe it would be simpler to ust clean up the 350 block and bolt the 305 heads on it. The smaller combustion chamber would boost compression without having to re-work anything. Its the most economical way to get a good running engine. Then save your dimes for a point down the road when a more radical build is in the budget. Good luck with whatever you decide to do.

For your modest goals and budget I'd just use an "RV cam" in the 205-215 duration range, clean up the bowls and chambers around the valve seats, run flat top pistons with the 305 heads, a moly cast ring set, a stock type timing chain will be fine, stock crank, rods, valve covers, rockers, pan, etc. I would step up to a m155hv oil pump, but otherwise mostly stock everything else except maybe some headers and as said mild work on the heads. Maybe a used performer or RPM intake if you can get one cheap, a plain jane 600cfm holley vac secondary carb, a rebuilt HEI ignition with a stock module and maybe a hotter coil, recurved of course.

Just keep it simple and you'll be able to get close to 1hp/ci on a shoestring budget.

Ok so I started taking the 307 apart and inspected the heads and they are not 305 heads. They are the "882" casting number heads with the big valves. Should put them in the 350 block and build it since they are bigger heads?

307

882 castings are 76cc chamber heads with smog controlled flow...which could possibly be the worst head ever bolted to a small block. I have used several of these heads on my race boat...as anchors!

You guys are getting off the subject. The question was can a person build a 327 with left over parts. I say yes, you got a 350 block, 307 crank and rods then all you need is 327 piston. As for the cam I used the old 447 lift 327/350 hp cam on a 307 that bored 30 over. It idle very nice with slight lope to it. The cam had a strong midrange torque. Put some 305 58CC heads and you really wake that 327 up.

Ok so I got side tracked off my project for awhile now its time to try and get something done. I can't find 305 heads to put on the 307 but I did find a set of heads with the casting #3795896. The guy said they are 283/327 heads. Would thes be any good on a 307. I can get them for about $200 rebuilt and ready to bolt on. Is that a fair price?
