Re: [BaadAssGremlins] Fw: Car is done but slow off the line also engine noise start up

[Rick Griffin <amc_poppy@xxxxxxxxx>]

Yep eighth mile.I drive the Gremlin for a friend after I sold mine.I like the 401s better but the 360s should run great.I am a bit puzzled by his 360 but do believe in a stall speed close to where your engine begins to pull hard.I wonder if he does have 4:11s It seems like he has a lot of lift in comparison to his duration.For years I ran a stock 343 280 horse 69 AMX with both 4 speed and automatic with 444 gears and 27 inch tall street tires. Ran a best of 13.39 with the stock cast iron intake in the late 70s.That car with the automatic had a stock converter but ran the low 13s with the 4 speed.Traction was not a problem and it would pull hard from idle with the stock engine and converter with the 444s.I drove the car everywhere and ran at 3200rpms on the interstate to run with traffic.Longest trip was from Staunton Va. to Atco NJ. in 1978 ran for two days and drove home.No problems! The 70s were fun!!!
Would really be interested to know what he finds out.Rick

I have been doing amc's for close to 25 years now. My previous build was a stock 140k mile  360 with ported heads, .236 dur @ .050 106 cl and .540 lift a 4K stall verter, 4.56's,  and it ran 12.6 @ 107. After 6 runs I decided 12's were cool but I wanted 10's. So now my pump gas street motor makes over 530 HP I have to fix the rear suspension now to take the abuse.

 With a gear like yours I assume your 1/8th mile.

I admit the compression is low and the 112 degrees dont help but if a engine starts to pull hard at 3500 rpms and the converter stalls at 2500 rpm [and thats giving the benefit of the doubt, most dont stall as high as rated !]you either go less cam or more stall or drive a dog!
The Gremlin I drive has a 5000 stall and a low compression 360 with a lot milder cam and it flat leaves but runs out of breath quick with 5:38 gears.We will be changing cams in the next day or so and heads as well to get at least 6500 rpm out of it.How long have you been doing AMCs?

More stall would require more cam and more compression.

112 cl may run better advanced a couple of degrees?Noise worries me ,was cam broke in properly?Does converter stall at rated RPM?I still think needs more stall to leave hard.I like a little stiffer gear ratio with a low stall speed.

Well baised on your cam and compression your converter is good. Sounds like you have a carb issue. The cam on the accelerator needs to be changed and possibly bigger squirters. Hard to guess not being there.

Its a mild lenati voodoo cam which is a 64501 standar base circle 484 intake lift 507 lift on exhaust: Duration 213.050 on intake. Duration on exhast is 220.050.  Lobe separation 112. Cam installed 0 strait up.  Has Headers has a EDL performer rpm air intake.    The car has a quick fuel 650 double pumper (similar to holley just shiny and has glass ports to see fuel.  It has a 2500 stall converter on the 1972 727 tranny.  Its a dog out of the hole even if you power brake but comes alive at 3000 to 3500 rpms.    I also ended up with a stranger problem.  when I first got this new motor back it made a metal to metal lifter noise (lifter not pumping up tappin noise) at first it  only did this in initial start. Now it does it when ever I start motor.  unless I just hsut it of and start it back up.  They said the reason It does this is the cam oling system they put in it bleedes down and has to pump up.  I have a bulltear oil pump plate that blocks the return bypass up.  Is that really usefull or is it causing  this probelm.  It has a TDK v8 oil kit for timing chain. a MDK oil kit for main bearings. The motor is a 360 from 1970.Rebuilt  It has 8.05 to one compression.   4.110 boar.  Stainlees steel valves.   Has a suplimental oiling kit according to  engine build ticket.
