Without writing all the flow figures down i will throw in a guess that between 500 and 700 lift with the ported LD340 it will range between 263cfm and 285cfm and within 5cfm of the head flow from 100 to 450.

Some of the aftermarket cast 318 pistons are far enough down the bore or that close to it that you could run a 360 (3.58) stroke crank with them and be at zero deck and 349 cubes at 30 thou over. I know someone who did this before stroker cranks became popular. If you have a 360 crank already...

Rough durations specs on the cam Brian? I'm just curious what it took to achieve the 500hp mark with the trickflows.

Hi everyone. I have two 69 Barracudas, one factory manual steering car one factory power steer car. Is there any difference in the two steering columns besides the length of the inner shaft that joins to the box? Could I just swap the shafts between the cars and leave the rest of the original...

I sonic tested a few and the best I had was a 76 casting, thicker than an early block I had. I also tested several 318 blocks and they were also worse than the thinnest 360 I had tested.

Back in the mid 90s i bought this 1966 VC Valiant, it had a 340 engine fitted but wasnt running as it was an early a body and needed work on the oil lines and exhaust given the narrow engine bay. In Australia the biggest engine option in this model was a 273. When i got it running i fitted a...

What point do you think it will become an issue with decent rotating parts or are you concerned about the oiling system?

Thanks for that, the engine seems to run very well with the stock victor 340 inlet, hoping that some porting will give it a bit extra again.

I saw the numbers on the ported victor 340 on the ported speedmaster heads, was just wondering if you flowed the stock victor 340 stock on the same heads. I might have missed that amongst the other posts.

Sorry for the multiple questions , is there a lot of potential available in porting the victor 340 inlet? A friend is running a stock one on a 408 stroker running ported cast heads and im curious if you think porting it will be worth the effort.

How do you think the ported speedmaster would compare with an as cast performer rpm inlet?

I think if i was to attempt this i would look at a pair of the later closed chamber W2 heads with the high 40ish cc chambers to get some compression into a stock stroke 318 with a flat top piston. Mildly ported heads with a 2.02 valve so they arent too big and a solid roller.

My 69 Barracuda fastback runs consistent 11.7s at around 115 to 116 mph. Mild 408 W2 ,10.5:1 comp engine with 3000rpm converter and 3.91 gears. Car is all steel and weighs 3300LBS without me in it. Would i like it to be faster, yes, but it is such a great street car that has been going strong...

What sort of duration is the flat tappet cam on the inlet / exhaust if you dont mind me asking?

Ok, was just going to mention that a friends 493 had a big rear main leak. They discovered that the arp studs interfered with the main seal carrier just slightly and they had to do some clearancing to get it to sit flush. No more rear main leak after that.
