is it possible to use the straight up Mopar A-4 for street if the cam is ground for a street application. I'd prefer to put something like that in instead of a 360 stroker.
The word stroker was cool in the 70s but now not so much. increasing stroke means higher piston speeds at a given RPM. That’s like going backwards when striving for more horse power. Increasing stroke puts more dynamic strain on the rotating assembly making RPM harder on a engine. The restriction in most Internal combustion engines is the valves. You can only fit so much valve area in a given cylinder bore. Making the bore bigger allows you to run bigger valves. Bigger valves moves more fuel and air. That’s why most modern hi po V8s run a bigger bore to stroke ratio. Some may say that stroke equals torque. To a point this is true, but if you look at Chrysler’s max wedge engines that made way more average power over the working RPM range than any Hemi could ever. You would see the Mopar big block wedge is a torque monster. It does so having a really big bore and a tiny stroke. Mopar RB and B motors had Small block chevy size stroke and made torque for days. Now in some cases adding stroke can help power output in some American V8s with less efficient heads on them but as a whole if you hear some one talking about how cool their stroker motor is they are a bit outdated
@@groomlake51 ...Offenhauser dominated the Indy 500 for years with under square four cylinders...they came off the corners so hard...it took the entire straight for cars with other engines to catch them...
Nice, i just built a Subaru Midget 405HP and 305ft lbs of torque, naturally aspirated, please check it out on my page, just first start up, but revolutionary
Half a V8 that produces the power of a V8.
Its some pretty serious shit.
id love to see a video of an engine build, particularly the block prep.
thats sick
Is this a Sesco chevy?
How many HP and TQ?

Im sure it is. See people running GM boat engines on the street. Anythings possible.

Is this an SBC sawed in half?
@@xmo552 no it’s not sawed in half you can buy the block from mopar it’s a A4 block
What was HP & TQ?
