That's what I was thinking. At the time, I thought the fact that both pulleys were the same diameter and both neutral balanced that it wouldn't matter. I guess I will get this thing installed and...

Forged Eagle crank. I never ran this engine with anything but the ATI Super Damper. It was balanced at the machine shop with a stock pulley and installed with a super damper that I purchased later.

The engine was balanced with a stock crank pulley and a weight flex plate. So it was balanced in the correct manner. When we assembled the engine, I wasn't even thinking about it and installed a...

If an LT1 engine is balanced using a brand new weight flexplate and a stock crank pulley, would it put the engine out of balance to switch to Super Damper? They are both neutral balanced, however...

The engine was balanced with the stock damper and the stock replacement flexplate but I switched to an ATI Super Damper before the engine was ever started. The damper does look like it's moving a...

It's not drive train related. We checked everything. Had the tranny at Janis Transmissions in Akron for a refresh after the incident on the dyno. We installed a new Yank converter, freshened up...

Once the engine is balanced, what can be done to correct an imbalance without tearing the short block apart?

Rotating assembly components were balanced with my flex plate and stock balancer. I'm not sure. Isn't there just one way you're supposed to balance and LT1??? Stock stroke crank.

So my new LT1 build has a BAD vibration. Caused my tail housing to break on the dyno. Shakes the entire car. Rotating assembly was balanced by a very reputable engine builder who built NASCAR...

Bumpity Bump!

Making a few changes in my combo. Selling off a couple items And have some extra parts laying around.

3800 Performabuilt billet 9.5" stall. Ran behind my h/c/i LT1 for 250 miles. Perfect...

Now I can. Just wait for the big bore block. It will open up new avenues for heads, intakes, headers etc etc. Plus the benefit with the current heads we have. 2000 hp here we come!

I can't post!

Really? An LT1 with full bolt ons, suspension mods and DR's should rape a stock 5.0.

You should run him in his new 5.0!

Hypertech programmer = poop. I was stupid and new to the LT1 game years and years ago. I bought one because it was the same price as having a dealership change my computer to compensate for my new...

My small cubic inch engine is a big thing for me. I think I have a good shot at 9's and I am honestly wondering if anyone has ever gone 9's with as little as 353 cubic inches, a roughly 3500 lb...

I want to get something like this, same style, but one that says Nitrous 353 LT1

No problem. It's always nice to give back. You guys are great!

Build something STUPID NASTY and go for the LTX N/A RECORD!

P.S. I'm still holding out for a big bore block... my 353 build is to surprise a few people and crack 9's in a small cube conservative...

What he said! Do it right and you'll only have to do it once! I'm speaking from experience. I'm running 11.2 compression and will be hitting mine with a 200rwhp shot. Most will tell you that more...

Hey Lloyd! I'll be able to let you know how my 353 21* setup works out real soon! Finally getting it ready for the rollers. Should be impressive!

EDIT: Also, surprised someone would stiff you...

Holy Crap! When I was running a 3200 stall tight stall, CC306 cam, stock heads and only half the bolt ons with 555r's I could pull a 1.69 leaving from idle in 3000 DA. That launch looks monster...

I built mine for high rpm and up to a 200rwhp shot of nitrous. Lloyd told me the few pounds of extra seat pressure wouldn't hurt me N/A.

I'm running a 237/245 .603/.611 lift cam and I believe the dual valve springs Lloyd recommended for me on my 21* trickflow heads had 155lbs of seat pressure. I wouldn't keep the ones you currently...
