I went hydraulic but if I had to do it again I would at least try to use a mechanical linkage. I already have some leakage issues and mounting the master and getting the rod angle and ratio right was a real pain...although I'm working on an a-body which doesn't have the aftermarket support that an f-body does yet.

I only went hydraulic because with a dart block, steel bellhousing, tremec transmission and dual plate clutch I figured there was too many different aftermarket parts involved to get a mech to work.

I think I'm going to try to run mechanical linkage. Thanks for the heads up on the headers Todd, I'll keep that in mind.

gmorris- I'll be running a factory GM block so I should be ok with everything but the headers. But thank you for the info on the hyd set up.

So I got the word today that the block I was hoping to use for my first ever big block adventure is toast. It has a spun main bearing and a crack in the same main web (saddle?) IT had also been hogged out 060 over already so even if everything else checked out I wouldn't use it. Now I get to find another one to play with.
Lucky for me, one of the guys on Chevelles.com lives next door to my best friend. He happens to be into big blocks (very into big blocks) and has another one for me to buy. He also has pretty much everything to machine it with except honing the mains. That will be farmed out.
So I owe a big thank you to the guys that sent me to that site. It turned out well.
Now I have another question. Heads. Has anyone used or know anything about Peters Performance Aluminum Heads? The Australian heads. The price ($1,699.00) completely assembled. Stainless valves,steel retainers and keepers, srings (for hyd cam), rubber/teflon seals, rocker studs and guide plates. 95cc comb chambers, 310cc int runners.
I have never heard of them. But I'm the new guy here.
Thanks,
Eric

I would prefer a well known machine shop did my machining and the heads were set up for your application. Meaning, camshaft and intended use. I have no idea who you are talking about and haven't heard of the heads. It could be great or vice versus. Do your due diligence.

I hear you Todd. The heads are something I just found out about today. The pricing was good but that only made me curious. I won't be using any off brand or cheap stuff in this engine. It will either be Dart, AFR or Trick Flow for heads. The guy doing the machine work has a lot of engines running around here ( I have seen many of them run at the races here and have known him for a few years via my best friend, we just never talked cars much before and I didn't realize he has his own business out of his home shop). So I am very comfortable with his abilities. I have spoken to a few people running his engines this week and they are also very happy with his work. We have talked a bit about what my goals are and he said the same thing you did, set it up right. Meaning matching the cam and heads, comp ratio, piston selection...
I'll be talking more with him soon and getting a specific parts list together. I'll post it before I start buying anything and see what you think.
Thanks for all of you help in this. I REALLY appreciate it! If you get up this way or I get down there, dinner and drinks are on me!

Sounds like you have have talked to the right people. Have you seen me drink?

70rs · #47 06-04-2009, 09:09 AM

Uh oh. Did I just sign myself up for bankruptcy if I take you out drinking?

Oh well. At least they don't allow drinking in the strip clubs up here. Those two are a bad mix.......

**tones2SS** · #48 06-04-2009, 09:15 AM

I think you're making the right move by sticking with DART, AFR or Trick Flow heads.
Good luck with everything. I've learned some stuff as well by following this thread, thanks to you & Todd.

70rs · #49 06-04-2009, 12:01 PM

I have learned a lot too. Todd has been VERY helpful in all of this. I just asked a ton of questions. That man has the patients of a saint.

I have a partial list of parts selected and am waiting on a couple of answers about some others that are undecided still.
When I gat the whole list put together I will post it so everyone can give opinions and maybe even take guesses where it will end up with hp and tq.
The goal is 600 for both. If I go beyond that I'll be looking at a whole new level of parts and HUGE expenses with engine internals and transmission issues. I have to try and keep some sort of budget on this.

Thanks to everyone for all of the help!

This is so cool. We have 5 pages of BBC chat with some really good info.
I know I will be going back several times to re read this thread.

I can't tell you all how excited I am to have a nasty big block between the fenders. This is my first one and it's going to be a blast to hammer on! Time to buy stock in tires and brakes!

(and hardly any mention of LS stuff, not that there is anything wrong with them guys

)
