95conv5.0 said:if i was using a a4 block, should i go ahead and get h beam rods, and forged crank?
or will 5140 forged i beams, and a steel crank hold everything i throw at it?
there will be no boost or nitrous used on this motor only n/a
95conv5.0 said:yea the afr 185s will be ported, the heads will be plenty big enough, thanks guys
it wont happen! He needs ALOT more head and spinning 8000rpms he is going to have to do a solid roller setup otherwise the hydraulic lifters will be starved for oil around the 6700 mark or so. The afr 185s are already cnc ported out of the box.....they dont get any better!95vert354 said:To go 10.0 in a 2900# car, your going to have to make about 575 hp at the rear wheels. Good luck getting 575hp from a N/A 302 with afr 185's.
did you read the title to this thread? is says solid roller right in it, and yes afrs do get better, alot better if ported, if you have ever seen the cnc job on afrs its good but not smooth at all, theres alot of work that can be done to these heads....Modular2v said:it wont happen!

it can be done with alot less horsepower with the right suspension!95vert354 said:To go 10.0 in a 2900# car, your going to have to make about 575 hp at the rear wheels. Good luck getting 575hp from a N/A 302 with afr 185's.
yes i read the title! i made that post at midnight and head my head lodged firmly up my ass95conv5.0 said:did you read the title to this thread? is says solid roller right in it, and yes afrs do get better, alot better if ported, if you have ever seen the cnc job on afrs its good but not smooth at all, theres alot of work that can be done to these heads....
but there is only a nominal amount of improvement to be made on them. . . . if you are going to buy some heads and port on them you should go with something that has more potential! Or just get some afr 205s and slap them on out of the box95conv5.0 said:did you read the title to this thread? is says solid roller right in it, and yes afrs do get better, alot better if ported, if you have ever seen the cnc job on afrs its good but not smooth at all, theres alot of work that can be done to these heads....

really? I have always been told otherwise.Thats interesting a good to know! i have been short shifting my 331 due to $hit valve springsEMW150 said:Hydro-rollers will go alot higher than you think. My 331 has been together since abou 2001 on the same stock Ford hydro-rollers shifting at 7,600 and sometimes 7,800 rpms. Stock volume oil pump with about 55-60 lbs pressure hot.

mine need a valve spring change BAD! i feel them floating around 6300rpm! I need new heads too really. It is a trick flow stage 3 cam so the ramps are pretty aggressiveEMW150 said:Keep I mind I run the Anderson hi-rev stuff which doesn't have the aggressive style ramps you run into with some custom grounds or like a Comp XE style cam. You can get into trouble if the cam is designed with ultra aggressive ramps. Valve springs are a big deal in mine too. I change them once a year even if they're not floating. That is imperitive to keep you retainers etc in good condition.

wow a 2mph gain in my case would put me a 128.....thats mid 10 second territoryEMW150 said:Yeah, you'll want to take car of that quick cause it's probably beating up your valvetrain bad. If you can feel them float they must be pretty extreme. When mine start to go I can't hear it or feel it, I just see it in the ET mph. It'll slowly just start losing mph till I change them then it's right back up. I've already gotten 2 mph back just from a valve spring swap.
