Does a 273 manifold fit on a 318 engine?

I have heard that the angle ont the intake side on the heads is not the same on 273 and 318,340,360. Is that correct?

66 and later fit 318, 340, 360. You Can fit an earlier manifold but not without work, mainly realigning the bolt holes to go angle, "Wallowing" it out. MT
 
Ok, now to the problem.

I installed 318 heads on my ´65 273 Barracuda. I got a Edelbrock dualplane with a Holley 600 dp carb.

The engine goes perfect with igniton 7 degrees before TDC, but i will not start.

Chaning igniton to zero degrees TDC it starts but it runs very poor.

What is the problem. Many motor-heads have been looking, but none could come up with some answers

:(

Check for slipped outer ring on damper

Does it start fairly easy at 0* Timing.
 
I always time by ear, making marks superfluous.
 
I have now tried with another carburator, but it made no diffrence.

I´m starting to suspect the ignition system.

For 10 years ago the breaker points where changed to a Crane Cam igintion box.
I´m now going to take another distributor and see what happends.

The Eddy LD4B is the one you want for the early small block, 273,318.

Just go with the Mopar Orange box and distributor. Never had ANY problems with that setup in my 65 Cuda Formula "S". Also have the same setup in my 66 w100 Powerwagon with a Poly 318.

I have borrowed a Orange box and a new (out of the box) distributor. I let you folks know as soon as I get some test result.

is it not cranking fast enough at 7 deg, or not firing? Could it possibly be a weak starter not turning fast enough or drawing too many amps not letting the ignition get the voltage it needs to fire?

It do not fire, but it cranks fast enough I think.
 
PROBLEM SOLVED ! ! ! :cheers: :cheers: :cheers:

Wiht a new distributor, a Mopar Orange Ignition box, new wires and my Holley it started immediately.

I have now the igniton 10 degrees before TDC and it runs good in the whole register, from bottom to top.

I think it was the Crane Cams ignition-box that failed.

Many thansk to you any how, for many tips and ideas.
