just saying hi new to the forum

Looking for some help with my first build up of a BBC
just some questions about the parts I have selected
ok here it is for all to laugh

started with an 89 mark IV block 4 bolt main
stock crank, rods, and pistons
3904390 closed chamber heads
been decked to 95 cc
supposedly brings it to 10.25 cr
pocket ported and enlarged to 2.19 /1.88 valves manley ss
pete jackson gear drive
jones solid roller 708/710 lift 250/256 dur @.050
1 3/4 headers w/ flowmaster 40s
edelbrock performer rpm slightly opened
and a holley 750 double pump
msd billet dist and 6AL box


I think the ratins should be around 560 hp @6000 and 540 tq at 4500
if this is wrong or anyone sees any probs in my future please let me know before I fire this thing off thanks Jim

Not much of a BBC guy myself so I'll leave the review for others. Just wanted to say welcome to CHR.... This engine goinin in the '53???

yes its going in the 53 it has a 77 camaro front clip and a narrowed f##d 9"
rear with mickey 31x18.5x15 with 4.56 gears think it should go fairly well

Sounds cool, welcome to the crew, i cant answer your question, but i know someone will be around shortly that can

thanks hotroddaddy I have a desk top dyno program and those are the numbers it gives me I'm just not sure of the flow numbers for the heads

Personally I would advise against using the gear drive.

Welcome to here.
I have talked to several poeple who got tired of the noisy gear drive real quick.

thats what I've heard from a lot of people especially Jim Reid my machinist so I think I might be switching to a double roller anybody see any other problems I'm hoping to fire it off this weekend

Welcome to the forum. Yeah, it seems a lot of people don't care for gear drives. Even my machinist says the same thing. I thought the principle was that they were supposed to maintain more accurate timing than a chain setup, but it seems this isn't what people are finding out in the real world.

Very confusing.

yeah I've heard the same but dont understand either anyone have any idea why ??

One of the reasons, and it's a major one, has to do with valve train harmonics. Check with Jimmy, being in the business, he may have a few more very good reasons.
