was going hydro roller but he is saying since i only drive the car 3 or 4 times a month that i should really do a solid roller and i really have always wanted one...... i can get my valve covers off in about 30 seconds per side and i have the little button switch to turn the car over while in front of the car already too...... shawn from virginia speed had a really good hydro can picked out but if i was maybe going solid roller would i want something else? i will find his specs in a second but my engine guy builds alot of engines and has something he probly wants me to run but i want to hear some more ideas on cams..... car will see little nitrous if any later on maybe a 100-150 shot if i get bored but im hoping it will be so strong i wont even think about nitrous for a while or even want it...... but i really dont mind having to adjust the rockers every now and then to get that extra power..... the funny thing is so many people try to tell horror stories having to adjust every week but most of those people dont have the right setup cause all of my close freinds that run solid roller adjust them about every otehr oil change and sometimes they still dont need them adjusted...... any more thoughts? jake

If you've got good poly locks, you shouldn't have to adjust lash very often. There's definitely more power to be had with a solid. What's the specs of the motor? Make sure you've got the valvesprings to support the solid cam.

im not 100% on the specs on the cam cause i just called him and jotted some stuff down but its a 248/252 at 110 LS and 600 lift the engine is a 388 stroker with 4340 all forged internals and has top notch valve springs..... the heads are dart 200cc that have been ported and polished to 215cc and victor jr that has around 8 hours of grinding in it....... brand new holley 700cfm double pumper with choke removed and 1 3/4 longtubes and magnaflow exaust is about to go on it......


on a side note do you think the 3 inch magnaflow exaust is gonna run and sound better than the 2.5 inch magnaflow? i can get it for abotu $70 more than the 2.5 inch....... i know if you go 3 inch with flowmaster instead of 2.5 it will be alot louder and sometimes too loud for street use...... but i know magnaflow is a mellow and smooth sound so it might even out........ jake

yep the basic flat tappet cam i had was gonna be good for around 500hp at the flywheel and this one not only being solis roller but better cam specs for a stroker should be closer to 650hp at the crank...... it will be done thursday and i will be working all night if i have to to start this beast of a small block! i cant wait to hear that cam do work!

solid roller and i'd be looking at the 4" mufflex with a ultra-flo muffler or true duals with 2.5" or 3" exhaust with turndowns at a minimum on a buildup like that.

Damn, what compression will you have?

i already run dual 2.5 american thunder kit but am going magnaflow 2.5 stainless steel!

anyone think i will have anything to gain from the 3 inch kit? its bigger and hard to fit of course plus alot more expensive so i dont want to get it if its only gonna make it louder...... it would be nice if the 3 inch would give it 10 15 more hp since its a pretty strong motor...... anyone ever tested this out?

kenSS

iTrader: (1)

never tested though but i 3" duals with dynomax bullets on my third gen. don't like the sound to much. i think 3 " for your application would be the way to go. just get some quieter mufflers.

i see me and you have a similar setup..... a newer street cruiser, middle age drag racer, and classic muscle car hot rod! cool stuff

yep bluebeast. little bit of old with a little bit of new. it's all good.

To date, my solid roller has never been out of spec more than .001-.002". It calls for .016/.018 lash and every now and then I pull the covers and feel them all with a .020" feeler just to see if they've opened up. Nope.....020" will not squeeze in. 20+ passes and a couple hundred street miles and no movement at all.

I have run a solid roller for several years in my street/strip Nova. I have good poly-lock rocker nuts plus a stud girdle that locks down on the nuts. After checking them several times without any noting any changes in lash, I let them go for long stretches without removing the valve covers. The days of daily valve adjustment are OVER.

thats all great news to hear guys! i cant wait to have my own solid roller stroker motor from hell! lol

Is that 650hp with or without Nitrous? If not, What compression and fuel are you using? And if you are planning to make 650hp, you're going to need a bigger carb. I make 589fwhp with bigger heads (Iron eagle Platinums M2 CNC'd), cam (254/257 .712" 108lsa), intake (Super Victor welded and port matched to Fel-pro 1209), and carb (Holley 950HP). I am however, only at 9.5:1 compression.

well when i say 600-650 thats just an estimate of course...... i have no idea what the car is gonna make on power but i do know it wll be good enough to outrun more cars than less..... but the car is setup with 10.5 to 1 compression and has some nicely ported victor jr intake and dart pro 1 platinum heads with the rest of the good stuff...... i should have the motor back in it next week and will strap it on the dyno and then i will let ya know what it did.......

Cool. I'm interested to see different combos. With real life numbers. I would recommend using a manifold vacuum gauge to see if your carb is too small.

I was just wondering why the cam is on the small side for 388 cubes? My 97' Firebird has a custom SR cam designed for 355 cubes that is bigger than that one. The motor is 12.16:1 compression and has the following specs: 282/288, 253/259, .640"/.640", 108 LSA, 104 ICL. I have found that my 383's have liked the cam in the neiborhood of 258-260 degrees @.050" on the intake side and 266-268 degree's on the exhaust side with the Dart heads. For your combo I like the 111 degree LSA and having your ICL at 106 degrees. I would also give your intake more lift than your exhaust, as the exhaust is more sensitive to duration. I hope your new combo gives you what your looking for!

With only 10.5-1 compression a bigger cam isn't going to give him much more power. Needs a bigger carb, I would run a good 750 or consider an 830 annular for that setup.

The cam selected is a little small in my opinion & even at 10.5:1 comp the bigger cam is going to run just fine for him. Also if the motor pulls hard enough the pressure drop on the carb will let it flow around 750-800 cfm.
