Double roller timing gears alignment direct fit?
Pulling the crankshaft front gear to replace with double row timing gears. Any suggestions on what to look for? The box only had the cam gear, crankshaft gear and the double chain. Also are these sets a direct fitment?

not near enough info. what box? brand, part number, etc. also what year car are we talking about? from your user ID, I can only "assume" an L98. FWIW, on my 85 iron head, I replaced the factory timing chain with a cloyes double roller - direct fit and no issues. bought it at summit racing. it was about 10 years ago - don't remember the P/N, pricing info, or pretty much anything.

I also noticed that the cam timing gear has a roller bearing plate on the back. Does the old block plate stay on?

Their parts seem to have a warranty/guarantee that ends "at install" -
I didn't see any warranty information at all - see the fine print in this link regarding their claim to "quality" - as long as it's in the box and NOT installed "no problem".

if your going to install this product, just set it up at ZERO ( the crank gear) and go from there. Same with the cam gear. Someone on here suggested to install he timming cover BEFORE installing the crank seal. Said it makes for an easier install on the bottom cover/pan seal. Its a good tip.

Hopefully timing set came with instructions. The multiple keyways are for degreeing camshaft, which is a little over the top for a novice. You can easily get cam crank timing incorrect, especially with so many key ways, that normally leads to additional repairs (more money) If kit comes with no instructions, you are unsure,or do not any a "mechanic friend of the family" to help you. Return it for a standard type set with one key way. The plate at the cam stay on it keeps cam from walking back and forth in the block while engine is running. Plate is only on SBCs with roller cams. It is easier to deal with front seal while timing cover is off car. This a Corvette, not a pick up, there not a lot of space to try to drive seal in to cover with engine in car.

Trimming lip on timing cover or dropping oil pan?
Was looking at pics on timing cover trick with trimmed lower lip. Can i drop the oil pan bolts without causing the gasket to leak later? Will the pan drop ok with braces intact? Really would like to leave the pan alone if possible. The timing cover kit i am using is two piece but will not install with pan tight.
