thanks Bob i love this stuff ..

also this is the sort of info im looking for..

am i correct thinking these later L99's are the same basic motor?

The easiest way to make a slug more sluggish, is to pull back the timing. So, your slug is slugging along, wheezing, begging and crying for some advance, but it comes too little too late. What's my point? If you give it advance when it really needs it, it will respond with a quicker, stronger rise to maximum HP.

Dr C am i correct in thinking a comparatively fiercer cam would be the ticket ?

in my head this motor could and should be alot more exciting than 110 hp ! Bob's link on you tube clearly showed that - but with the 90's version..
thanks !

If it looks like a duck, walks like a duck and quacks like a duck, it's probably a duck
Or is it
Outwardly, a 262 SB Chevy looks the same as a 400 or any other size SB, so unless you spill the beans or get caught up in a drag race, no one will be the wiser as to its displacement. (Except that it will make fewer stops at the gas station )
Of course, we'll never tell ....

Standard hop up techniques. 4 bbl carb and intake manifold. Long tube headers. Do a Doc recurve on the distributor. Going inside, add a torque cam, more compression. With the small bore you can't use big valve heads. Maybe a small chamber 283 power pack head cuz you don't need big ports for 262 cu. in. Too much cam will kill low end torque which that small inch engine needs.

Frankly, I wouldn't do much to it because you won't get much bang for the buck. Dress it up. Wait for a 350 or 400. Unless you are like me and want to satisfy your curiosity.

I've been doing research for hopping up a sbc 307. One of the common upgrades is to swap to 305 HO heads. This would help a 262 even more as they have TINY exhaust valves. The combustion chamber on 305 heads is 58cc which will help compression.

A friend had one in a Monza with a 4-speed & he slammed in a hot cam & it perked it right up!

Do you remember how big of a cam he used? Was it big in general or just big for a 262?

I keep seeing people say it is really easy to over cam a little engine.

I've been doing research on cam size for a 283. Same idea, took big of a cam or valves and the thing is lazy. This is the cam I'm going to go with, it was highly recommended by several guys that have used it in a small cube SBC. Hopefully the specs can be a good guide for you. Should give decent sound but also perk it up without being too much cam.
