C2 SBC Exhaust Manifold Bolt

[Brian Monticello]

I need one ram horn exhaust manifold bolt and am about to place an order with gmpartsdirect.com. They list two parts:

3841724 @ $3.20 qty 1
3733134 @ $2.08 qty 5

Anyone know which is the right part #?

Thanks!
Brian

It depends which bolt you need; 2 different length bolts are used for small blocks with "ram's horn" type manifolds. The end bolts (2 on either end of each manifold) are the "short" bolts. These are GM #3736035 and are 1-1/4" long. The 2 bolts at the center positions are the "long" bolts. These are GM #3733134 and are 2-27/32" long.

The GM #3841724 bolt is 3-11/16" long and is not used for your application.
