standard pinto with twin 40's. running the transit dizzy/ignition set up.

Will it have a rev limiter inbuilt? ie like some of the CVH dizzy's did. If not, what is a standard 'safe' limit to be revving it to?

And where is peak power usually achieved on this sort of set up?

No point spinning a stock Pinto past 6250 as the cam will have run out of puff well before that 5800 I think is peak.

fair enough, thought it'd be around there.

Should be plenty for the time being

when you thrash the standard pinto the valves start to float and hence you can't over rev it, but it does rattle rather a lot. I tried to break them in the past and never managed and even if you strip the belt you simply fit another and carry on, cool engines

Std is about 5,800.

Take mine to 7k regularly. Not gone pop yet....

I pull 7600 regularly on my one with a high lift cam and a few tweeks, biggest problem is when you rev beyond this the bolts in the big ends stretch, a shell slips and it all goes bang. Its worth putting arp bolts in or upgrading to steel rods if you want to rev it harder. Some of the f2 guys are reving past 8000 rpm.

Standard re-built engine happily revs to m self imposed 6250rpm limit on every gear change. Not much going on power wise over 5600rpm though.

7k on mine regularly, no problems as yet

Are you guys revving to 7k running a standard crank or a steel one?

James

Standard crank.

If its a 205 injection block it will happily take 7300rpm. If its and earlier block then 6800rpm is generally regarded as the safe limit.

Ok, so now I just need a cam to make use of that information
