The Official Hot Rod Thread - Part 2: No Replacement For Displacement

[Brad69]

Let's see going to hit Walmart I need eggs, bread, milk , Chevy crate motor!

I have never seen a stoker Pontiac 350 that would be different and cool.
I did see pictures of an Olds stroker this old dude around Indy put together He had to order rings or something like 10 times before he got the right ones.
If it was a Chevy you guessed it Wal Mart!

Way the hell back in the day we made up our own strokers. 327 small journal cranks in 283 blocks 30+ over. I can not remember where we got the high wrist pin pistons as I was not involved in that part. "Old" guy that was helping us did all of that. I screwed them together. Duntov 50-50 solid lifter cams with 327 fulie heads that we pinned the pressed in rocker studs. Oval stamp rockers (triangle stamp rockers would die a horrible death) pink rods and blue print the oil pump. These things were right at 11.5 to 1 CR. You had an honest 6500 RPM street screamer. You could push them past 6800 and they were still holding the nose up but approaching critical mass on the rod caps. An 8" Harmonic balancer seemed to level them out.
These were basically a DZ 302 in a 2 bolt main block.

Try and find that in the cake isle at Wally.......

Does the Poncho have more torque than a chevy same CI's

 

[churchmouse]

I suppose I could look it up.

Looking at 1970 ratings, 455HO was rated 500 ft lbs, LS6 454 was also rated 500. HP was different with the Poncho at 370 and Chevy at 450.

 

[RustyHornet]

Same year but lowest performance 350 2 barrel: Poncho 255 hp 355 tq, Chevy 250hp 345 tq.

I was thinking the rotating masses of near the same weight should be close in actual numbers.
Cam profiles/head and manifold design will have some effects.

Oh, I have driven/rode in a few 455 HO's.......370 my ass.

 

[ChristianPatriot]

Screw it, I’ll quit fooling around and just put together a stroker big block Chevy.

I’ve been telling him a drop in stock 455 will do what he wants with the right gear.

Finding one is the key. A good one.

Only people that would be upset are Pontiac purists. And honestly, those people are seriously getting on my nerves. Do what you want man, I’d urge you to go BBF power just to **** more people off. Or Mopar. Slap a 440 in it.

Truth. Always a shot in the dark being that the last 455 Poncho is 41 years old...

 

[RustyHornet]

He already knows that 350 has a good home if he pulls it before spring.

I figured as much.
I have some parts if he wants to go that way.
I would screw the short block together for him.
If he went this way 400 plus is easy peasy if he follows a given recipe. Very streetable and no stall required. A stall is always fun and yes it will get the Poncho/Nova cross breed off the mark quicker. These are cheep. 2500 for about $250 made local. I have one for the 64. It is actually a 2800 but that would be a bit stiff for many folks.

We’ve got a better chance of the Rhinos and Donkeys agreeing on someone that that man making a decision.
