A friend recently ran a 408 with the comp 268 cam crappy x heads and manifolds tq carb, poor exhaust in a convertible Dart. With 3.91 gears knocking on 12s in the quarter.

So December no trickflows.

Does anyone know when these heads are due out.

Thanks

Timing cover is solid no block off plate.

Yes normal la timing cover but fuel pump factory blocked off.

I have a roller cam LA head 360. I think it’s from around 1990, 1991 not sure. I don’t know much about these engines. I would like to step up to a bigger cam. Do I run a magnum style roller cam. And where can I find more info on these engines.

I think it has slipped as the lower pulley doesn’t wobble on the solid part of the balancer.

I recently purchased a 71 D100 that was converted from 6 to small block. I have noticed that at idle the balancer has a wobble. I checked for crank walk it seems good. When rotating the engine you can see it as it closes the gap with the timing marker almost touches then back to an 1/8 in gap. I...

I'm just wondering if I should coat again with lifters or use something else I was hoping to fire soon but got held up and saw this. Also wondering If I prime engine wont that just wipe everything anyway.

I just lubed up a new cam with comp cams cam lube the runny red stuff left it for a couple days didn't install the lifters yet came back to install them and the cam is dry lube is gone. Not sure I have any faith in it. Where did it go I want to install lifters but the motors going to sit so I'm...

OK been searching the Manley and Ferrea site cant find a 2.02 11/32 5.30 valve. Anyone have a part number. Went through all the different type valves nothing close.

I need to see how the heads check out. Thanks

Thanks

Ok, Thanks

No valves yet. They are long valves. wondering what length they should be.

Hi, I am building a set of w2s and am wondering if I should run the stock size 3/8 diameter or go to the 11/32. For a motor that will not see more than 7200 rpm is there much gain for cost on the smaller diameter valve.

Thanks great input. My plans are 3.58, W2s. using what I have with the set ups im running now.

Im just looking at 6500.

Anyone know the max rpm for a scat cast internal balance crank. Thanks

I think you should look at this question differently. 340 vs 360 what does it take a 340 to run say a 360 in say an 11.00 drag race. Stock stroke both engines iron heads not w2. I run 340s because thats what i have. Iknow obviously that the 340 will need more gear and rev alot higher. Im...

This is an interesting thread. I have a 340 Duster I drag race. 340 has been raceed since the 70s. It runs 11.50s-11.70s. Have to rev the hell out of it. When its time and I can afford Im looking for more cubes.

Lucky13, Does your shop do any serious head work, porting. Ive got some w2 heads I need done.

Ive had the opposite problem W2 heads that had the intake side milled so much that you need a spacer to run them. My bad on the purchace, didnt see the surface cut. Even though I asked if there was any machine work done. Got screwed on Ebay. Never again.

Thats what I am going to do. Trouble is there arent any good local Mopar! machinests.

This is an eye opener for me i have a 410 short block been sitting on my stand for 3 years. Eagle cast crank. My machinist ground the crap out of it. It wouldnt balance. He ground the same location on crank. And then externally balance. Im afraid to run this thing. I looked back up the part...

I ran the Shumacher poly mount. I only run it on the drivers side, Stock on passenger side. Cold start you feel a little vibe but once everything warms up you dont know its there. This setup works well.

I understand the interest 30 years ago all I had was a 273 in a 68 barracuda notchback it was tired I had the hipo pistons more compression. stock heads cast tq manifold and tq an old PAW grind cam 280- 480 Auto 4.30 gears. with bad tires a stock convertor remember it was a tired engine it went...

Wow, great responses thanks.

Anyone run edelbrocks out of the box with success. I here they need to be torn down and checked at the guides and seats. I want to run them in stages on my 340. Stock then port them. Thanks
