Scamp408 OP master S Joined: Feb 2005 Posts: 2,709 NJ central	I made a post on sunday and I guess I should have been more clear my bad. my junk right now is running in the low 11s and I think Iam at the max et with my eddie heads.I have a set of Indy cnc 230 heads and the matching hardware to go with it at my disposal.Should I put the heads on and run it,they should get me into the 10s or should I just save them for a new short block.The motor in the car now is a good motor with about 50 runs and internal balance.It has probe pistons a mopar cast crank and eagle I beam rods.Do you guys think the rods and the crank will hold or am I playing with fire?No power adders put on later just all motor.I am only looking for 3-5 tenths or am I dreaming that with just a head swap. Thanks in advance and pinch me If I am dreaming.

I think with the other heads, your cast crank, may or may not handle it too well. If it were me, I would save those heads for another build, or put them on. I just wouldn't run it that way for too long.

(about 395 HP) It might be in there already with some sharp tuning but, the heads, more than likely, have the HP corked up. Good tire/gear selection. What are the rest of your cam specs and CR?

Open up the heads/valve job A little more stall wouldn't hurt but, not necessary. I'd keep the 28"tire/4.10 gear......especially w/TTI (1 5/8"?) With bigger headers, open exhaust probably 10.70-10.80

I was going to just put the head on but I have been reading all the stories about eagle rods snapping.

At you're weight it should be in the 6s in the 1/8 now. My old hydraulic cammed, pump gas 340 went mid 7.20s with a best 1.533 60', it normally went 1.55-1.57. 69 Dart, 3300#, 9.5" 4400 converter with 4.30 gears.

Unless you have fuel delivery problems or really low float settings, my guess is, a combination of cylinder head and small exhaust is currently keeping you from running 10s. 11.17 is pretty quick for 117.55 MPH especially, since you have mediocre 60 fts. There is something definitely choking off the power on the top.

Everything has to be right and matched to get them to run how they are capable of. My old 416 combo was a 260/266 flat tappet, 560/580 lift that i ran 1.6 rockers on(made it 598/623)it was on a 108, in at 104. Weiand excellerator, mildly ported eddies(maxed at 274 at 600 lift) TTI 1 5/8 step to 1 3/4 headers 8 inch convertor that flashed about 4900-5000, 28 inch tire with 4.30 gears(they were too steep, would have liked 4.10 like you have better)had a 1025 race demon, that was a great carb for that combo, this all was in a 3400+ pound car with full interor and bench seat, column shift at 11.8 compression. car went 10.74 at 123.70, through the mufflers so at 3150 pounds, it should be extremely easy to get in the 10's with a combo similar to the above, even if the heads are just mildly cleaned up. The above all said, there is no way i would lean on the combo you have with those eagle I beam rods amd that cast crank for any extended period of time and not expect you arent going to drive over the bottom end at some point in the very near future. So, i would step up the cam to something with 600 corrected lift and 260 ish on the intake, consider going to a 950 ish carb and perhaps more convertor, after you fortify the bottom end to handle the expected power you are going to have on tap..... I took that bottom end on my 416 above( h beams and cast crank and threw w5's on it) and changed nothing except headers and intake and went 10.30's with that swap,and proceeded to drive over the crank and ruin the shortblock, so your indy's should net you a similar gain if you have everything corect with the eddies you are currenty using and make that swap. Strokers like cam and carb, you are lacking on both currently, as well as having a solid shortblock foundation to build from.I might leave it as is until you get a good shortblock under it.

I know several guys running mopar cast cranks going 10's who have broke them, I had it happen to me personally, and know several guys i have raced with that had the same thing happen. And in all cases it was with better rods than the original poster has(which may well be an even weaker link than the crank is. Yes, MAYBE somebody somewhere has gotten by like that, but my personal experience and that of others i personally know is that the advice i gave him is very sound. And putting INDY heads on that shortblock would be an out and out no-no. Last edited by B3422W5; 08/04/09 01:17 PM.

I ran a set for 125 passes and was glad they made it through the season. It's not worth the risk for me to test their longevity. I was glad to sell them for $50 5396920-DSCN1708.JPG (15 downloads)

That motor doesn't make all that much power since I was told by her that she didn't want it to be to fast that she had to wear a fire jacket or put a roll bar in the car. Was shooting for 7.70's in the 1/8th and wound up with a [Email]7.39@91[/Email] so far in great air. She only turns it to 5500rpm and motor has been together for two seasons now. I wish I had put the Scat's in it, shoot I wish I had known about the Scat's beforehand.

I guess it's possible the broken SIRs I've seen were just bad heat lot flukes but, I took them out at the end of the year.........after seeing several posts on the subject. I ran Ross 99626 domes (567 grams) 7400 RPM every shift and the occasional 8000 limiter burnout.........so they can't be complete junk. Just didn't care to test what others had already found out. Personally, I'd never use them again.......even in somebody else's engine. 5396966-DSCN1590.JPG (15 downloads)
