Default 302 chevy

Why is it i have this constant desire to only build a roughly 302. Is it that it can't make a lot of power destroy a high tin, nodular iron cap factory block i have lying around. Is it my Little Mouse name. Or is it i once had a new one. Must be the rpm screaming in my head driving me nutts. I have to be over the edge to keep wanting to build a 302 lol.

If you want a over square engine why not do it with a 350 crank in a 400 block?

Or how about a 477? 4.5 bore x 3.75 stroke Big Block

As you probably already know, 302s' were really just 327's with 283 cranks to get em' into the Trans Am 5 litre class. High revving small displacement track motors are really more for that purpose. On the street, larger displacement with more low end torque's, usually the ticket.

Yep; a 377 is an overlooked combo to be sure.

Although, in the end just a straight 350 built to turn 7,500 RPM can be an amazing beast

Still - the buzz of a high-revving SBC has it's own appeal

I set there and think about it becaues i only have a 4.00 bore block lying around i also think a 377 would be a great engine. Never built anything for myself smaller then a 331. Friend and i long time ago in a shop we had rented built a 348 using a 400block main spacers and a large journal 327 crank. Even with the poor heads of the day it was amazing how the bigger bore cylinders helped the 23 degree heads unshourding the valves. Built simular 4.030 bore 355s you could easly tell how the big bore block had helped. Now its easy to see why to fudge on head flow numbers the companies use 4.20 cylinders they know will never happen lol. I noticed atleast they admited it on some RHS heads in there advertising.

I have three four bolt main blocks two of them are the better tin, only one with the nodular caps. Cost to machine is so high these days can't hardly see using them.

No doubt cubes always rule.

What pisses me off cool stuff like the 69 trypower i had on my 454 bought it for $125.00 dollars, spent $15.00 for three holley carb kits to rebuild the carbs used it around a yr sold it for $100.00. Now look at the silly prices. A cross ram for a 302 unreal.

You too?

Truth be told, I was too chicken to punch out my '64 283 block all the way .125" to get 302 cubes. I only went .090" in case the cylinder walls had shifted during casting. I still call it a 302 though. Nobody would know what a 297 was.

You will probably have trouble finding parts associated with the 3" stroke. Lots of Ford 302 parts listed in Jeg's and Summit but nothing for the bowtie version.

Yep been looking for awhile. Came across an Edelbrock piece it looked like a CR but had the single carb top, lost out on it on ebay. Sold for under 400.

Wanted a crazy badazz 302 for my 67 Abody just love the motor but knew it, because of the weight woulda been a pig unless I was WOT all the time. Built a high winding 358 that shoulda gotten it done well..60 miles later it was pulled and now a stout 385 going in.

Do have a virgin 400 block and thought of doing what was posted here just not sure if I trust the main webbing on those blocks to spin up that high reliably. Like the concept of short stroke/long rod/spin it hard and not care about it deal. Torque be damned when that tach swings out of control! lol

Still love those little motors!!!


Still want a crossram on my motor just because. Maybe setlle for a tunnel ram or some weirdo intake piece

[/QUOTE]While getting a bit off topic, now you know why LS swaps are so popular, as actually weigh 120 lbs less than iron headed small blocks. Thats not exactly a chump change difference.

I agree that unless the motor is being built for a specific purpose for high revs, more cubic inches will always be the preferred way to go on the street.

Just as a point of discussion, I have heard many times of the revered high nickle high tin blocks. What indicates that this is so? Sorry this is a loaded question as I know the stock reply concerning certain casting marks under the timing cover, but the origin of these marks may not be what you think they are.

I have a 302 and while it is a lot of fun to run it hard it is a real bitch to get the car to climb my steep driveway on a cold engine.

imo the whole high nickel block thing is so overrated. Small percentage diff really. Any sbc block should do so dont let that hold you back.

yes LSx engines are better but it will never appear as a Gen1 with a ratty solid lifter FT or even solid would.

Might be interesting to build an LSx 302 and carb it but something is kind of lost there.
