There is no special machining to install solid roller is 400 SBC. Retro lifter mean after market Hyd Roller lifter. Now if you chose to use 350 Rods in a 400 you'll need to be sure order small base circle cam for more rod and cam clearance.
You will need the retro rollers..... and new pushrods........
If you do decide to go soild roller just make sure you don't "over cam" it.Quote:

Eric, quote; "don't go to big', glad that your keeping on eye on me!!! Yes, I was probably thinking 'too big'. What would you say is the BIGGEST cam that I could go with; 413 cu. in., 10 to 1 compression {my 'forgot the what you call it' compression is a little under 8.5 to 1 {dymanic?}, AFR 195 heads {but I was also thinking maybe bigger AFR heads, the 210's?}, dual plane manafold {but I'd go to single plane}, 3000 true stall, 4:11 true track rear gears. Cam now is 230/236 @ .050 duration, .522 lift {w/ 1.6 rockers}.... Is there a reason why you can't go to big w/ a sollid roller that's a different why you shouldn't go to big w/ a hyd roller??? THANKS, Bill
NO you need RETRO roller lifters ONLY for going in a older flat cam engine not set up for GM stock hyd roller block... Soild Roller you do not call them retro just the hyd rollers. I WOULD PUT A BIG ROLLER CAM IN THE DAMN THING PUT SOME CR TO IT if not why bother with it???? you have a light car it is not like your going to pull a fifth wheel with it ???
With your comp. ratio,stall speed,and gear ratio. you might as well run a hyd. roller cam.Quote:

I would keep the 195 cc heads but I.M.O. it would be a toss up between the RPM Performer and the Victor intake above 4,500 RPM'S.
......THANKS ;) Pat, I don't want to get to carried away cuz I want to run pump gas. As it is my motor pings like crazy on regular.... Eric, ok so I'll look for one that's not more than 240. I though the bigger heads would be better with a bigger cam? Guess not, but that's ok as it's cheaper to not change them :)... Isn't the single plane better at higher RPM's?? Bill
Sorry,I wrote that very poorly.Quote:

I would not even look at the bigger heads un-less your wanted to turn the engine above 7,000 but you don't have the comp. ratio to support it.
....Thanks Eric, Nope, don't want to spin my motor to 7000!!! I'm afraid at 7000 it'd spin my parts right out the bottom end! AFR has a new Eliminator head that they say puts out way more HP & TQ. It comes in a 195. I'll try to attach a link...... Oh Eric, Would you use the Victor or the Victor Jr. ??? Thanks again, Bill

Yes,the Eliminator's are great heads.Quote:

I would run a Victor JR with a 1 inch open spacer.

415 CID 10:1 Comp. Sportsman 210cc heads Crane solid roller .556/252*565/260* at .050" Victor JR Demon 750DP. Pulls like a big block and i get 18 MPG.I have had this engine in the car for 7 years. Good luck Chris
He has already stated he does not want a 7,000 rpm engine.Quote:

He does not have enough stall at 3,000 rpm to run a cam that is 250 at .050
yes thats a big cam 050 mild 250.. i would say he will not care for it much at low rpm
