Stroker options

I'm not trying to argue
I don't know exactly what redlines are these days
But I guarantee the 302 which was usually being shifted around 7500 is not a high Rev no not at all the 283 and 327 might have hit 6500 if they were lucky
Also the de stroked engine made close to if not more power then the engine it's block cam from
The 327, sure the FI back then made 360
But the 290 hp rated 302 made an actual 355 and performed as well in terms of acceleration as the PIG Block 396
I don't want big stroke
I want a small block I can shift at 7-7500 @45-50 lbs of oil pressure
Rpm like I was with the 350 that was in the c-10
I had before it was totaled by my dad
It's called a solid cam gentlemen
I understand roller is what most have these days
Solid cams may not even exist anymore
But that's how you get +7000 RPMs all day long with an old school small block
Cause when the 302 was created I don't believe roller cams where what they Are today if they even existed and had been proven from 67-69
So my question is yes can I de stroke a 5.3 buy putting in a 4.8 crank then going to town on heads and cam and all that good stuff
If I do that
I'm looking for somewheres in the .230/.230@.050 and like .543/.525
Something along those lines
If not more duration
.540 life is getting up there

325 hp , 350hp, 375hp and 375 special hp(425 hp). All were 402 cid All cars had different tachometer redlines up to 7000 rpm's. That's when you should shift btw. 50 zl1 1969 Camaros were made (all aluminum blocks)all good for 60 ft of wheels of the ground performance. Lots of L88 427 vets putting out 550 hp advertised at 425 horses to fool the insurance companies.

I've ridden in 500hp 396
Chevy big blocks are pigs go ahead and say all you want I don't care what kinda power they made
They never ever moved liked the amount of power they had
They are all dogs I'm Not gonna change my mind I'm not gonna argue
I' have my opinions on big block Chevys
And until I see a 454 or 396 or 402 or 427
Run like the Pontiac 400 I one had then I may agree until that time nothing will change me mind on big block Chevys

Freaking auto spell
The 67 corvette I had a ride in with a 427 was screaming to be shifted at 6 and by 7 I was surprised it didn't blow, and it was a stretch to get it too 7

You could get an LS7 block and put in a 4.8 crank. LS7 has the biggest bore and 4.8 has the shortest stroke. You would wind up with a 349. Anything is possible with money. Wouldn't make any sense and would be a total waste of money and power but if it's what you want, do it.

they make some really lovely diesel battleship that have cylinders the size of the cars on this board. Tell me how the install goes.
or barring that tell you what drop a 454 old school iron block in your car with a 1 barrel carb...and tell me how THAT goes.
There is NO substitute for a well thought out and EFFICIENT build. If you can't use your cubes your pretty much pissing up hill.

"All bbc's are dogs" ? You have to be kidding me. First, stating that 305, 327, and 350 sbcs use the same block / bore? Anyone that knows anything about a sbc know the 305s have a smaller bore and different blocks. And trying to mimic an old sbc setup with an ls engine is a waste of time. Gone are the days of ".500 lift is getting up there" i built a 350 sbc with vortec heads with a .480 lift cam. Get into the ls crowd and you realize this is all old tech. A .600 lift cam is nothing for ls's. Listen to the experienced people on this board before you waste your money. A 4.8 is still bigger than a 4.6, btw. Youll still be beating stangs with a bigger engine regardless lmao.

If you just want to spin an engine to the moon just get an ls6 head and the shortest stroke crank and biggest cam and bore (ls iron truck block) you can find . btw the 302 sb only came about because of racing LIMITS in classes Chevy wanted to race in at the time 1968-69. ford 302 same. The gto was fast because at the time it was allowed by gm to have less weight and more cubic inches than any other gm car 1965-66. Corvetts got all the cid (427 aluminum heads), light weight and suspension in 65(396 cid)-66. Nothing was as fast stock from gm .

"Originally powered by a naturally aspirated 477ci big-block, the Malibu laid down 660 hp and 700-lb/ft of torque at the wheels despite having to run factory Dash-8 cylinder heads on 275 radials as Factory Street rules required. The result was mid-9-second e.t.’s at 140 mph, and a lot of upset opponents at the track."
How fast was your Pontiac 400 again?

I get a kick out of some of these muscle car stories I here. Just yesterday somebody told me about there friends brothers car back in the day pulling the tires off the ground. From my experience on the drag strip it takes lots of traction to make that happen. I would say impossible on street tires no matter how much power it had. Ive seen a 302 powered Camaro at the strip that was built to the factory specs and it was a dog. I have a pretty nasty small block in my drag car and was in denial about how much better the LS motors are until I went to a dyno day with some buddies. I will not **** away another dime on one. I am now in the process of putting a 6.0 into my chevelle. Ive built SBC's and taken a 5.3 apart. I cant believe how much better the LS motors are from the factory.
