+2 hp , but after 1330 you'll have an expensive rebore but the 1310 can just be bored to 1330

[Artful Dodger]

Go for 1310. (nearer to 1312 actually ;)) you havnt made the most out of it so why use up more block for 2 hp? Put a more manly cam in it ;)

[holmesy]

me and you think very alike lol

i like your thoughts
do you think a 276 kent will do? feels good to be honest, the torque figures seem to be better than the 286's?

[Klevdo2202]

Why not 1293? you can re bore it to 1312 and 1330 then....

[holmesy]

ive chosen 286 for mine, 1310 cc, 10.5:1 comp ratio

[Artful Dodger]

^my god snap.

I'd go for a 276 if it's used a fair bit

286 if you don't use it all the time.

296 if you a real man;) (don't do that it's a race profile)

[holmesy]

mines my daily , I just like that style of driving

For a road engine where a couple of BHP are not important it is best to go up 0.020" at a time until you have a 1330 which needs re-boring. Then you just sleeve it back to 1275 and you have, effectively, a new engine at standard size.
The only real reason for going straight to 1330 is when you need that extra couple of bhp to knock a couple of tenths of a second off a lap time or to reduce the time 'up the hill' when hill climbing.

I have a 276 in my 1330 and its a nice all round cam without revving the nuts off it to keep it above 3500rpm, bit lumpy idle will do every day and still produce power.

i think 1310 is a good medium, but what power would i expect to get? with a large valve head and a ported polished head?

thanks

[holmesy]

with a 276, and a good head say 36 exhaust and 30 inlet, a compression ratio of 10.5:1, hif44, lcb.

you should be expecting round mid 80's

[Hegnirst]

The 276 is a '*******' cam, the only cam I've ever fitted for anybody else, that hasn't resulted in disappointment is the 286............

well you cant of built them very well then! sorry but that is complete balls

[Hegnirst]

I've ordered the 1310 :)
