I vote for a LS headed sbf. Any ex274hr sbf cams for a donation?

Has Mopar Performance discontinued the 5.9L crate motors? I've scoured their site, but cannot find it. Thanks!

1 had a 63 tempest station wagon back in 75, 4 cylinder engine. Bored it out to fit 400 Pontiac pistons. It ran good until I totaled it on a rainy night on a sharp curve. Wish I had it now. I had found a 4 barrel intake, but didn't get the chance to install it. Cool motor, and drive train.

I'm surprised you didn't replace the cam bearings ,oil pump and crank gear

How about a stock 400sbc long block with a cam and intake? roller cam upgrade since flat tappets as daily drivers are a liability these days. 91 gas if needed. Then do all that with basic head upgrade. We want daily drivers. The most power in a DD thats reliable.

Which has better low end hp and torque thev truck norris nsr cam or the Btr bigger cam

No replacement for displacement👍😸

1:47 High mileage LT1 guys... I learned the hard way this thing will kill your'e engine. Not this part but the gear on the other end that drives the oil pump. Mine was worn super thin after 180k of hard miles. I cranked it up one day and the gear teeth had worn so thin they sheared off when I started it. no oil PSI = rod knock. killed an otherwise still good engine. After my fiasco, I'd recommend you pull this thing every 150k and replace the gear on the other end. GM PN# 19052845. It will save your otherwise good high mileage engine from destruction.

0:47 that's the coolest looking intake ever on American small blocks.

TPI is the coolest looking intake any american small block ever had.

Have a great week Richard

A cross-flow ls3 based head would be really cool on a 292 inline 6 based engine...

I'm surprised you haven't done a ls coil pack dyno test. Rumor has it the round coils with heat sink at the top auto fire causing engine failure on the dyno.

Test the motor with the same stuff on fuel injection

Nice video 🔥🔥🔥

Hahahah. These are always the funniest projects when there’s nothing to lose and everything to gain. I miss doing pointless stuff like this. It gets nerve racking when there’s a 30k$ engine on the dyno. This is more just for fun.

Love to have a x-ram for my lq4 powered 2500hd

Hi, thanks for all the hard work test to give us these numbers. What formula do you use for sizing your injectors?

If it's for a certain 6-cylinder I can throw you a little money

Why not make compression higher like 14:1

An incorrectly specified cam will be insensitive to incorrect timing. You have to test to find out, because you don't know what you're doing.

I'm actually doing a copy cat of this build, and ran into a hitch with the rotating assembly, if anyone has suggestions for a modestly priced kit, PLEASE reply with it here.

What's that thing got? Square gears? Also fuel pressure is really low in those so your gonna be lean.

You stated the L78 cam equipped with a 3310 holly 780 my factory 396 425 was equipped with a 800 cfm holly from the factory never seen a L78 with a 780 ever from the factory

Kool..put an ls head on a Windsor

If you get a chance could you run the 292 with one of the aftermarket manifolds and the stock 1bbl. carburetor. I think it would be interesting to see what only changing one thing would to the torque and hp curves..

The corvette 396 425 hp engine use corvette only exhaust manifolds you ran a more restrictive manifolds

More power sooner. When racing, every split second counts!

Make a single cylinder for Brule's go kart stuff. It'd be cool AND I'm sure he'd absolutely love it for the familiarity in tuning.

Would a 671 be too small or would the results be similar

sent the money for a cam

no BOV,that aint gonna end well

Has anyone proved the world products sbc/ls head hybrid blocks worth getting ive been wanting to see dyno numbers on similar setups just traditional sbc headed vs ls headed sbc

Fantastic work

I’m running one of those chilly bombs on my turbo k24 , it can’t keep up on constant pulls , but kinda works ok for the money

If it's a SBC cam count me in for the 200. The shirt is just icing on the cake🇺🇲

All you have to understand is that every engine is boosted. "NA" engines are boosted with 1 atmospheric. So higher boost doesnt change anything. Thats why all calculations are done in absolute pressure.

Iron duke? AMC 4 cyl? AMC 258 I-6? LoL

ls Heads on the 3800?😂😂😂

Can you do some ls carb dyno tests? I’m planning on making a carbureted setup for the ls. Thank you!

LS headed RR Merlin LOL

None of these 3. The 351 Cleveland 4V is the greatest small block V8 ever made.

Everyone looking to swap the spider would be looking for a intake manifold while your in there.

Could not get the live feed but I do have a couple questions about the 347stroker ,seen some top end kits that have canted valves and the stroker pistons to match which would be a 347. Boss wondering if I have to use the intake for the kit or can I use one of the 302-289-5.0 intakes i already have?

I'm going with the 8.1

Hey I got a crazy question boss. If I have the new 4.3 v6 2014 and up could you use a 3.8 v6 crank to de stroke the motor?

Not a Chevy guy but just like any other engine would be to get the lightest rotateing assembly possible that will be strong enough and then the highest compression for the type of fuel you want to use and then the most fuel and air you can get into and out of as possible, of course a stroker is an option, especially if you can keep it light as possible but that's pretty vague and generic without knowing much about the LS engine of course forced induction will increase power as well as adding cubic inches

Ford...LS..some mopar..PLEASE PLEASE go back to the 5.9 magnum

This is y chevy needs bail out money and not ford all do respect just think about it

I know this is a few years old but the torque specs on the retainer plate on the Gen 3 Aluminum engines was 18 ft lbs not 10...
