    4.3L Cam & Piston Advice

    Hi guys, I have pulled my old 4.3L from my 19 foot Regal ('89) due to a faulty block. 11 years was a good run for it. :) I have done some upgrades over the years, and here is where the engine is to date: 4.3L Normally aspirated, Non Balance Shaft, roller cam. True Vortec Heads 1:6 Roller...

    4.3L Coupler Inspection?

    Hi guys, While I'm waiting on my motor, it occurred to me that I probably need to inspect the engine coupler when I remove the old engine. What should I look for on this item as far as wear? The engine is an 89 4.3L 4bbl carb. Should I replace with new or reuse it? Seems awfully old...

    4.3L Repower

    Well I'm waiting on parts for my 89 4.3L repower... (second one) :) I have a few questions. Last repower I just farmed out. This one will be all me. I plan on stripping off the heads, manifolds and intake before removing the old block. These are new and will be reused. Removing the block...

    New 4.3L short block time

    After 12 years the bottom end decided to give out on my old '89 4.3L. Looks like the block is cracked. This will be her second repower. LOL The good news is that the top end is completely new. New Vortec heads, roller rockers, intake, carb and manifolds. Sooo, I called up Rapido and...

    Redesigned Exhaust Shutter Fitment

    Hi everyone, I went out to piddle on the old '89 4.3L and get her put back together last night. I found some brittle exhaust tubes so I have bought replacements. My old exhaust shutters were not even in there so I bought new ones as well. The problem is, these newer style shutters don't fit...

    Manifold questions...

    Hi guys, As you may recall, last season I was dealing with a water intrusion issue into my cylinders on my '89 Mercruiser 4.3L non balance shaft engine. I had installed some Vortec heads and GLM manifolds after finding water in #2 cyl. The new build up resulted in more water intrusion on...

    Motor Removal

    Well, if any of you were following my older thread, it looks like my 4.3L must have a crack in it somewhere, so I'm pulling her out for a pressure test. Shouldn't be an issue, as the heads and manifolds are already off, but I've never lined up the engine/outdrive before for reinstallation. An...

    OK, now I'm just plain mad at my 4.3L

    Was due to do a little carb tuning this morning on my 4.3L . Decided to muff it in the yard and just adjust the idle mixture. Motor would not start. Hydo locked. W T H? Water out of #3, 5 and 4. Traces on #6 plug. Ooooooooo I'm POd. Pulled the new manifolds and I'm having them pressure...

    4.3L & 1409 Carb Tuning

    I'm not happy with my carb tuning and will be dialing it in this weekend. I am running the Vortec heads on a non balance shaft 4.3L with the Edelbrock 1409 carb, performer manifold and 1.6 RRs. She just seems lean on takeoff. The carb is equipped with the 1409 4.3L calibration kit, .089...

    Question about towing

    Well, it looks like my other half needs a new trailer for her marching band... she's a music teacher and band director. They have been towing the band gear with a little 8-10 foot single axle trailer. I found a really cool 21 ft. tandem axle Haulmark on CL, but the curb weight is about...

    Shopping for a houseboat

    Hi guys, I've decided that I like the river system so much that I want to be out there in the colder months as well. Soooo, I'm looking for a used houseboat. I have never owned one, but most seem to have I/Os. Some come with dual 4.3s, dual inline 6's, and some with dual 5.7s. Am I correct...

    Heaven is noisy tonight

    Jen lost her Grandfather this morning. He was a member of the Greatest Generation, who flew the F4U Vought Corsair out of Pearl Harbor, HI. Somewhere in Heaven, there's the roar of a methanol injected, supercharged 18-cylinder Pratt & Whitney R-2800 Double Wasp Radial announcing that another...

    4.3L Vortec Conversion

    Well I have almost finished my 4.3L Vortec conversion. My 4.3 L is a non balance shaft, and the bottom end was gone through a few years ago by Eagle Racing Engines (Cup engines). So when I cracked a head, I took the opportunity to upgrade the top end. Took her out last night and she did VERY...

    Water in 4.3L Oil Pan !!!

    Hi all, I have an 89 4.3L Mercruiser Alpha 1 non vortec. I always change the oil before the season starts, but coaching baseball this year means I'm just now getting to it. :p The boat is kept in a heated garage in the Winter. So I never bother to drain the block. Been fine for over 10...
