Valve lifters…solid/hydraulic/roller tappet/flat tappet?

[CHANMADD]

I use a little talked about kit. Rev Kit .......What this is , is a set of springs between the head and the lifter. This keeps the roller permanently in contact with the cam.....no skidding or bouncing liters. Also now you can still keep a low spring pressure at the valve because the valve spring has only the valve itself to control and not the whole valve train . This is also going to prevent broken rockers etc. I have stock , springs that come with the Edelbrock heads and can rev happily 8000rpm. I do have the proper components in the bottom including a full balance job on all the spinning parts.

So how much horsepower do you think you're making at 8000 rpm?

I hope you're not using the retainers and locks that come with those Edelbrock heads...

That is the truth of it...... I very seldom rev to higher than 6000rpm, it just is not necessary.......I built the motor for racing , but have as yet not got on the track...yet! I did do alot of track in S.A. and won some trophies.
But you are right no-one needs an 8000 rpm motor in a Cobra for the street,Hell there is a thread here asking how fast guys have taken their cars and most have barely been over 100mph, (thats barely out of 2nd gear)......so yes 350 HP ,6000rpm in a Cobra is actually plenty power.
