I also would like to know what length the primary tubes should be? I was thinking about 26 inches but since I do not have the engine it is hard to say
Thanks for the reply.

I am looking for 4 left and 4 right .225 offset norris stainless steel rocker arms 1.6 ratio 7/16 rocker stud. I am putting a 331 chevy motor similar to what the Grump had back in the day. I also have a set of PRO MAXX 225 aluminum heads that I want to use. If I cannot find the Norris intake rockers...

I am wanting to change the rocker ratio on my big block chevy. I put light springs on both int and ex valves lashed the int valve and checked clearances at the appropriate 10 degrees btdc and atdc settings. Int was .098 with .028 lash Ex was .160+ . so my concern is with the int as the new rocker ra...

Thanks for all the replies.So the retainer height is added to the installed height is what I thought would be the correct method. THANKS garym

I have a Rimac valve spring pressure checking tool and I have a question. When checking the seat pressures of the valve springs I have the retainer on the springs when I check the seat and open pressures. So if the retainer thickness is say .100 thick do you add the retainer thickness to the install...

I plan on some up grades to my 588 chevy drag race engine.I have talked to three different shops about a sheet metal manifold for my engine and they need the cylinder heads to do the manifold. I do not want to take the engine apart as it only has 8 passes (1/8 mile) and I don't think that the motor ...

thank you for your reply.I do not like the idea of retaining the cam bearings with small allen set screws.Are these set screws on each side of the cam bearing and are the holes drilled in the block as made or do you have to have a machine shop do this? It is 17 weeks fora block! thank you again for ...

I am considering building a big cu in motor and was hoping if someone here could post a couple of pics on how the Babbit cam bearings are retained in the block. Also are the roller cam bearings preferred over the Babbit cam bearings and if so, why? I really enjoy this forum. THANKS garym

I am rebuilding my 454 chevy for my c30 truck.The pistons that I have are sealed power hypereutectic #H518CPO3O.On the box the piston to wall clearance said .0015 which I think is a little too tight but I thought I would get some input here.As far as honing the cylinders what grit stones would you u...

Thanks for all the input. I have ordered the sealed power H518CP+.030 hypereutectic pistons enginetech moly rings , engine bearings,and a FelPRO complete gasket kit for under $370 dollars which I think is pretty reasonable.So now I have to price out the machine shop prices. THANKS garym

Well I need to rebuild the 454 engine for the crew cab. The short block was a chevy factory rebuilt (AC DELCO) .Crank is .010 rods and mains.The pistons are cast and I want to have the block bored .030 and honed.So I was wondering what the quality of the Enginetech hypereutectic pistons are P/N P501...

So I need to buy intake and exhaust valves for my 331 cu in sbc and I would like to know if anyone on this forum has used these valves (Howard Cams extreme black valves) and pros or cons on these valves. They are made in India according to their website and I was wondering the quality etc.The motor ...

A few months ago I asked if anyone had any pics of how the babbit cam bearings were retained in the cam tunnel of the 5 in. bore space block? Planning on doing a 738 or 761 engine and have not decided on babbit 60 mm or 55mm roller cam bearings.A few pics would be great along with thoughts on babbit...
