    Unbalanced exhaust cooling temperature...normal or not?

    Problem solved! During a test run of my engine, one riser was staying much cooler to the touch than the other, and I thought I had an exhaust cooling system malfunction. Turns out I simply wasn't forcing water into the system fast enough for the starboard riser to get a strong flow of cold...

    Can I use a V-6 outdrive with my V-8 setup?

    Hey Guys, I'm actually pretty well versed in this matter, but wanted some opinions. Here's the situation. My Sundancer has a very ratty outdrive that has terrible electrolysis related corrosion and is probably nearing the end of its serviceable life. I was going to buy an SEI drive of the...

    Difficulty replacing rear main oil seal

    I know this should be ridiculously easy to do, but I'm stumped. I have a SBC with one piece rear main seal. The engine is being rebuilt, so I already have the seal housing off, and the old seal out of it. My dilemma is I'm using a Victor Reinz seal, and it is double lipped. So I have no way of...

    454 BBC vs. 6.5 turbo diesel in truck?

    Notice: This is a LONG post...read at your own risk of apathy! :D I frequent farm auctions during the winter looking for deals on tools and miscellaneous parts. They almost invariably have beater pickup trucks at these sales, so I went prowling for older model Chevy trucks for their ubiquitous...

    Funny "TLC needed" boat ads on Craigslist.

    Re: Funny "TLC needed" boat ads on Craigslist. OK, I'll bite...I think there is a very good possibility that at least a few C-list ad's we see are deliberate attempts at humor. We spend so much time looking for these gaffes that some clever folks have decided to pull our legs with outlandish...

    Fuel pump dilemma

    Guys, I am about to pull my hair out over this issue! Would someone please tell me if it is truly necessary to use a bronze tipped fuel pump rod if converting from a stock flat tappet cam, to an aftermarket roller? I have asked many sources, and I get both yes and no. I'm wondering why there...

    Do you reuse head bolts?

    This has become another engine rebuilding dilemma for me. I have searched many Chevy hot-rod/racing forums and the responses are almost 50/50 for/against reusing head bolts. Here is the specific question for the poll. If the heads in question are OEM Chevy 350 Vortec's and use TTY (torque to...

    Help with purchasing decision: Exhaust manifolds!

    Hi gang. Well, I made the ugly discovery of fine cracks at the bottom of both my manifolds the other day, and am prepared to spend mo' money on my aging tub as opposed to JB welding and risking a blown (new) engine or wet bilge. I have looked at all of the offerings, and already know that I DO...

    Using "old" lifters with new cam?

    Is this truly a no-no? The reason I ask is, the Merc manual says "IMPORTANT: DO NOT install used valve lifters if a new camshaft has been installed." Well, that simply sucks because I spent three hours completely disassembling and cleaning 16 hydraulic roller lifters by hand! I have to replace...

    What is 454 Alpha 1 gear ratio?

    Hey Guys, I know the 350/260 Alpha 1 is 1.50:1 Did the factory installed ('87 & '88) 454/330 Alpha 1's use the same gear ratio? If not, can I use one behind a 320 hp 350 without undue stress or harm? This is on my express cruiser. Thanks!

    Mixed ratio rocker arms?

    Hey Guys...who has opinions on mixed ratio rocker arms in a Vortec 350 build? Specifically, I want to run a 350 Ramjet/383HT cam #14097395 with 1.5's on the exhaust for standard .451 lift, and 1.6's on the intake for a .459 lift. My reason for keeping stock exhaust lift is a 1.6 would take me to...

    Engine lifting points...

    Hey guys, when lifting a motor (350) out of the tub, do you use the two attachment points on either side of the intake manifold only, or do you trust the one bolted to the thermostat housing. On my engine the lifting loop on the thermostat is huge, while the intake loops are tiny. Just curious...

    Rapido raises prices

    Has anyone noticed? I've been trying to get on their website for 2 days...finally it's back up. I immediately noticed that many engines went up $100 across the board. I guess either the economy has been hard on Raul also, or demand for his work is on the rise?

    350 to 454 upgrade?

    After doing a search on this subject and reading about 20 mostly unrelated threads, my eyes are glazing over...but I will risk asking the question. Is a direct swap of a marine 350 to marine 454 an uneventful task, or must a number of items be replaced to make the exchange successful? My biggest...

    Auto vs. Marine motor assemblies?

    I know that this topic has been visited in a variety of ways, but I hope to generate more specific answers to a troubling question. Other than the obvious external parts, like starter, alternator, distributor cap, power steering pump and exhaust system...what are the key cost differences...
