First time engine build won't fire

[QUOTE="BOXHEADgumby, post: 1972395999, member: 38833".............. had put the timing chain on the wrong mark. ...........[/QUOTE]

Don't feel bad others have done this, and we had one guy who was sold a reverse rotation marine cam. On those multi-keyway advance/ retard timing sets it's easy to make a mistake.

So far as the intake leak, I do not use the front/ rear seals. I clean things really good and put a really thin coat of sealer around the water ports......frontmost and rearmost ports. I lay a "big fat" RTV bead across the front and rear. CAUTION........Some Edelbrock manifolds can leave a big gap in the front make sure you look that over. After putting it down and getting it mostly tightened down, take a towel/ finger and smooth the front and rear silicone beads, then let it sit unfired for at least 24 hours
