Finally got around to upgrading my clevo, had the old combo for 2 years. Want to get the new one under way over the next two weeks.

currently is:

- fully rebuilt 351 with 302 rods flatop pistons
- lumpy hydraulic cam
- ported iron 2v open chambers with adjustable roller rockers
- 750 Vac Sec Holley on Torque Power Dual Plane Manifold
- MSD Billet Dizzy
- Pacemaker Tri Ys
- Toploader and 3.9 rear ratio
- this combo did 235rwkw

want to change to:

- crane 246 solid cam and lifters
- 750 Barry Grant Speed Demon
- CHI 2V 190cc Street Assembly 8005A

after taking to a couple of workshops i think this is a good combo. the reason im going the 2Vs is that im probably after heaps of low down torque, and want to keep the Torque Power Dual Plane (it wont work with the 3Vs)

my question is do any of you guys see any probs with this combo. any idea of an estimated rear wheel power output would be appreciated.

also not looking to restart the CHI v AFD thread...just looking for some advice

It should go very well. Gammaboy had a similar combo (185cc CHI's) and made over 400rwhp. I don't think you'll be disappointed at all.

I think the inlet manifold might let you down slightly, A matched CHI manifold or funnelweb might be a better option.

I would use a camshaft of John's recomendation.

If you are after "heaps of low down torque" that manifold will be spot on. I would probably get a cam ground to suit your needs. The F246 is a great generic cam, but i bet you could do better with some looking or CHIs imput. And with low down torque in mind, maybe the F238 or similar may suit your needs better.

I must agree with the others, get John to select the cam, Gammaboy gained 50kw when he changed to Johns preffered cam.
And John gave me a choice of 2 with my new setup, i chose the one with 500 extra rpm :) who needs low down power with a 5k stall.

As all above let john help with cam .I know I will get him to do my next cam when the time comes

G'day,I would look at going to a single plane manifold and speak to John at CHI for a cam. I have one that he suggested, problem is, i am yet to do a full power pass.

thanks for the advice guys, going to speak to John again on Friday and make sure ive got the cam right. i agree re the manifold not being optimal. but it does give me shitloads down low!!! (good fun from the traffic lights in canberra) really looking forward to the new heads, heard great things about the CHI. John from CHI couldnt be more helpful
