roller or flat tappet

Hey guys, I have always been a fan of flat tappet cams, especially solids. But i am working on a new motor. So this being said, i am considering a solid roller cam, not really large and it is streetable. I don't mind the maintenance because i have had a motor fail from a broken valve spring. I have never had a flat tappet cam fail either. I have a friend whom put a retro fit roller in a sbc and had some problems finding the matching timing cover and button, ending up spending another $130 for a matching set.
Have any of you guys installed a retro fit roller in a BBC?
Or should i stay with old faithful flat tappets.

With the BBC's propensity to roach flat tappet cams, you must have some real good kharma. Buy a lottery ticket.

I used a Crane timing set with a torrington bearing,the Comp part is quite similar.I use a stock timing cover,just dent it with the appropriate size socket to get a little end play,app. 0.005-0.010.The upper timing gear will wear into the front of the block without some type of thrust washer or torrington bearing,and they are available seperately,like these;

Maybe you could hunt around and locate a 454 with a factory roller cam. This would kill 2 birds in one stone and would be cheaper also.

I would forgo the dented stock cover and get yourself a good billet cover. Your cam and valve timing will thank you.. The hex-adjust timing sets are great for dialing in the cam timing while degreeing it.The cloyes billet cover offers a set screw for ease of endplay adjustment and a cover that comes off in case you want to adjust your valve timing with the hex-adjust whilst not removing the timing cover or disturbing the oil pan seal.

If you just want a streetable car why not a hyd. roller? there's not a need for a solid roller if you don't plan on running a really agressive cam.

Many years ago I stuffed a 468 BB into a 86 Trans Am with hydraulic roller cam. I used CompCams roller timing chain set that comes with the three piece Torrington Bearing. The backside of the cam gear comes already machined to account for the thickness of the three piece bearing, so it's a direct bolt on and fit behind the stock, stamped timing chain cover without a problem.

I used the roller type thrust bumper to control forward cam movement since I'd seen the solid type actually drill a hole in the T/C cover.

Car was a daily driver and I never had a valve train problem.

Hope this helps.

I hope this helps out I am running a 350 sbc wich I know it's not a bbc but same concept and I am running the retrofit style roller cam and if you get the cloyes timing cover you will love it. All you do is after you have everything in place and buttoned down you just take a scredriver and tighten the roller button till it makes contact with cam then put the cam button outer screw back on and your done. Endplay will be where it needs to be. I have had no issues with using the cloyes cover and I am also using a similar timing chain for my setup using the torrington roller bearing with the comp cams locking bolt plate. Go roller you won't have to worry about wiping out a lobe and can just pour in oil and go.

thank you guys for the info. The block seems to have provisions for a factory roller type retaining plate. but it had a flat tappet in it. It has two threaded holes with nothing in them, right where the plate would bolt. I have tried to find a sbc plate to fit and it don't work. The block is a four bolt main, two peice rear main out of a 1985 3/4 ton truck. If i am not mistaken.
