I’m using Crower now, seem to be great but only have about 25 passes and 1200 mile on them so far, don’t know if they are bushed or needle.

Hi again , An update, we have just run a PB 9.52. @ 141.70 , basically 2 tenths and 3-4 mph better, main change was 200 lb weight loss and some Indy tunnel porting. To refresh memories the car is a street strip Aussie 4 door Valiant 440/528, na on 235/60/15 radial rubber. Our Drag Challenge 5...

Yep, do what DVW Doug said, they are a pushing pump not a pulling pump, get rid of that glass filter and insulate lines from hot area’s.

Looking forward to running at this track come Drag Challenge Oct Tex Good luck

Nice Put your 950’s on it now !! I’m running twin 950 APD carbs that are beautiful but wish I went for 1050’s

Do you mean I will see a big power difference between the current SR’s that are 360cfm and the dash 1’s at say 380cfm ? I was going to buy Huges offset rocked rockers as I’m using them now on the SR and they are great. I will look at a new cam around.750 lift up from our current .700 , can’t go...

I do have another new cam here that I picked up in a group of other parts, it’s a Comp roller 289 289 108 and would be 716 lift

Hey Doug, Cam is R280 4468-8 , 446 lobe x 1.6 is 713 gross and 690 net lift . We go through though traps at about 7200-7300 rpm.

Don’t think so, -1’s have a straighter port that’s why you need offset intake rocker

Thanks for the replies, So if the SR’s are 360 and the 440-1 are 380 in real HP is that around 40-50 ?

think I’ll give the B1 a miss, yes 572-13 is 4.5 I think . If it’s 440-1 do I go 325 cfm or 345 ? Do I go bigger valve (2.25) or not for my combo ?

Hi all, Looking for a little power, (always) for our big block. Currently 440/528 4.375 Molnar crank, Eagle rods, kb 12.6-1, maxed out SR heads 360 cfm, Huges rockers, .700 net lift solid roller, Crower lifters, Indy tunnel , twin APD 950 carbs. 3650lb but dropping 200lb out, has gone 9.69@139...

We run Hughes Ali 1.6 on our 500+ Indy head engines, they go to hell and back running in Drag week type events, they have been amazing .

Ah Doug, seats are both plastic hornet in front, stock rear. Just looking at the last on the rollers dyno, had 400hp at 5000rpm and 580hp at 6000rpm so the converter swap could be good

Yes,, it’s the game we are playing, good challenge getting a car to hook
