Re: LOW TORQUE LS Engine Build

Clevite makes .001 undersized bearings. You can use a standard upper and a .001 lower to tighten them up .0005. Or in no.5 use .001 upper and lower to get back to .0025.

Looks like an aluminum block so align hone isn't an option.

Or in my case a CM DD Ford guy, THE TRIPLE WHAMMY!!! LOL

Most importantly an LS engine is just a Windsor wearing a Bowtie!

Re: Manifold air speed

Heavy, so we currently do not have the adapter brackets for BBF. Stuska has them in stock and would probably a week or better to get them. That being said, we would like to see the print outs of your engine's dyno session to see if the values look correct for afr's, egt's and bsfc (brake specific fu...

Re: Manifold air speed

I thought about a restrictor plate, but didn't want it skew the results. Thought it would disturb the airflow to much and not give a smooth fuel charge. TRUST ME I DIDN'T WANT TO SPEND THE 800 EITHER BUT I COULDN'T STOP THINKING ABOUT IT!!!!!

Heavy, we only generally work Mon. thru Fri. I can talk to the boss and see if there's exceptions to the rule. What size is the engine? Maybe some specs on it? Diggin, we can ride all the way up to Wauchula and beyond. Down to the Gulf of Mexico through Charlotte Harbor. Don't believe there's a limi...

Re: Manifold air speed

So here are the results of my water test on Sunday. Throttle response from 4 barrel to 2 barrel was more crisp and clean, 4 barrel had a lag, 2 barrel has virtually none. I left the pitch alone until we made our first stop, wanted to see how many rpms I gained. With the 4 barrel, wide open was 2800-...

Re: Manifold air speed

Cause at the time I got it for the 302 they didn't have a 2 barrel option. Since working at the engine machine shop and getting experience with the new dyno, I've come to realize alot of things! Carb size is often oversized on engines too many times.

Manifold air speed

So as with most things, I can't seem to leave well enough alone! I got to thinking about manifold air speed in relation to rpm. The equation for determining cfm requirements of an engine are as follows: displacement × rpm × volumetric efficiency ÷ 3456 = carb cfm. So I plugged in my numbers. 408 × 3...

Re: I'm Building 2 Stossel Boats with High Torque Motors

Ok well maybe I'm a little overzealous. lol . Never weighed it with all the rest of the stuff. I will weigh it when it comes off to go on the new hull complete. She was full of oil at 439.5. It's close but not close! haha

Re: I'm Building 2 Stossel Boats with High Torque Motors

Put a stroked out Windsor on #2 and it might become #1 lol. Seriously I'm getting about the same power out of my 408 as a 540 straight valve and with less weight! Fixing to change up the injection system to pull some more power out if my theory is correct!

Re: Caddy 500, 4bbl carb or Holley Sniper?

Block off the heat cross over if it has one! Snipers don't like the heat, seen a few of them lose the internal fuel pressure regulator. Sniper might also benefit from an open plenum due to the way it picks up vacuum signal.

Hopefully not but if you do give us a holler, we'll fix you up! Yeah this one had the KB's too! Not what we would call a severe duty piston like a gearbox boat should have. Of course it did not help being WAY LEAN! If the ratios would have been correct probably wouldn't have melted down. Forged just...

Blueprint 383 rebuild.

If you all followed my thread on the 408 I built, I slipped in some pics of another engine in the shop for rebuild. Blueprint 383 that nuked a couple of pistons and had a high volume pump that was chewin the distributor gear to pieces. 20190319_133944.jpg 20190319_133908_Burst01.jpg 20190328_074625....

Re: new 383...what oil

Synthetics are designed for newer power plants in my opinion. They don't seem to get along with old style gaskets and like to leak. Just my opinion. LS is fine with synthetics but not old sbc's. 40 psi at an idle is WAY high for my liking. Probably has a high volume pump which is also not needed unl...

Re: new 383...what oil

I run Valvoline VR1 Racing 20w-50 on a direct drive solid flat tappet 408 Windsor. Joe Gibbs also makes flat tappet oils. I like conventional oils, no synthetics for me! Any idea what weight the break in oil is? 10 psi per 1k RPM is the general rule. If you know what's in there now and idle pressure...

Re: Air fuel ratio for direct drive

On my Windsor I drilled a small hole on the side of the stat. It sure helped with the air purge. There is a funnel from Lisle tools that uses an adapter to the radiator cap that will let the system run and bleed off air. https://www.summitracing.com/parts/lil-24680/overview/ I also run a product cal...

Re: Air fuel ratio for direct drive

With a dual plane intake air velocity is created for down low power. The throttle body is still introducing fuel in the same place as a carb. Port injection I agree should make no difference since the fuel is sprayed directly in to the port. But on a throttle body I believe it makes all the differen...

Re: Air fuel ratio for direct drive

Self learning systems bolt down to any square bore intake manifold. My 408 has a standard Edelbrock Performer dual plane intake that has a power level from idle to 5500 rpm. These systems do well with either single or dual. If I were to gearbox the engine I could run a single plane to move the power...

Re: Air fuel ratio for direct drive

Awesome. They come with an adapter plate to clamp on the 02 sensor for people that don't have the provisions to weld. I highly recommend a true weld on bung. Have not done a LS setup yet. The throttle body will work with a carbureted manifold, but I'm not aware of electronic support for the ignition...
