Re: Briggs Animal hone and piston to wall.

Some of those can be a real pain to keep straight. I have a few stones that I have cut down to as short as 2" As far as the finish goes some of those small engines dont want a real smooth finish so I guess just go by what the manufacturer says. I usually go 150 to .003, 220 to .0005 and then 280 plu...

Toyota 4.0 1GR-FE heads ... anyone happen to be working on some ?

I know this is a long shot but does anyone happen to be working on a set of these heads ? Need something checked.

Thanks,
Bill

Re: Electrical system troubleshooting

Travis,
Take a look at the mirror lights in your sunvisors. Make sure they are not staying on. My 99 Tahoe was doing almost exactly the same thing and I finally figured it out after walking out into the garage with the lights out and caught a glimpse of it :)

Re: Testing for a worn timing chain

Travis, The big single roller chains in those engines seem to last forever without stretching. My 99 Tahoe has 280K miles on it with no issues at all. I have had some marine engines with over 1000 hours of run time and the chains still look about the same as new. Are you having an actual problem or ...

George,
I have looked through every book I have here and cannot find a thing. Maybe a picture would help someone recognize it ?

Re: 283 pistons, #7003, sealed power??

Is there anything in the inside of them ? I have a bunch of old catalogs and interchanges at the shop. I will take a look in the AM if nobody else has answered.

Re: hydraulic lifter valve adjustment

On most engines it really should not make any difference at all as long as the lifter "plunger" is somewhere in the middle of the travel. I think the only time it is real important is when you are revving the engine to higher rpms and there is a chance of valve float. That is when the lifter can hol...

Re: SBC LT1 / vortec compatability

ph, I would make absolutely sure that the LT1 cam will work in a "regular" roller engine. I am pretty sure the front of the cam is different for the Optispark. Every cam manufacturer I looked at has a different set of part numbers for the LT1&4 It may be a simple matter of using the correct timing s...

Re: sbc ideal water pump pulley diameter?

If I remember my engineering classes correctly from a million years ago the only thing that will increase pressure in a closed system would be increased temperature. Increasing the water pump speed would increase pressure going into the front of the block but then it would be balanced on the other e...

Re: Elongate pushrod slots?

Bob,
The Luis tool is for elongating the old style "slots" The LT1 heads just have big round hole that the pushrod passes through so all you need to do is take a die grinder and get whatever clearance you need. I am not even sure if the Luis tool would even work.

You might want to check the locks you have. I think they might be +50 locks because of how close they are to the tip of the valve like Dan said. If you go right to a -50 lock it might be too much. Post a close up picture of one, should be easy to tell.

Looks awful close but they might be +50 locks which would move them up like that. I would think that as long as there was some clearance it shouldn't be an issue.
