Ive been slowly collecting parts over the last year and half, and my new motor is finally coming together. looking for some comments about it, or what i might need to change before its all put together
396 Sbc, forged H beam eagle rods, forged eagle crank, forged Srp pistons, stock 2 bolt block with billet splayed caps installed, thinking about filling the block to the bottom of the water pump passages. The heads are Afr 210 eliminators with a 72cc chamber milled to a 70cc chamber, im not sure about the springs the machine shop is figuring that out for me. The cam is a comp Magnum
304 hr ground on a .900 base circle .600 lift .245@ .50 on a 110 lsa and comp retrofit hydraulic roller lifters, comp told me they would be good to 6800rpm but ill probably be shifting at 6500rpm. i went with a victor jr manifold and im not sure about the carb yet im looking at a holley 750hp but im not sure it will be big enough. the exhaust is hooker long tubes 1 3/4' primaries to a 3" collector then reduced to 2 1/2" through an x pipe and then 2 moroso spiral flow mufflers.Im also not sure if this exhaust will be big enough or if i should build a 3" system for it.
I got a free, almost brand new tci th400 with a reverse manual valve body and a T-brake. i dont have a converter yet so i need some help with that im i was looking at a 10" converter that is supposed to stall at 3800-4200 but i think that might be too high for me. So any advice or comments about my combo will be appreciated.

I would not run a tall filled block besides on the track, nothing to cool the oil. we try to push mine to the start and tow back after the run. I dont know what application your building it for but HR cams are for the street and trans brake manuals are not

yeah, this combo seems a bit mismatched.

i feel it needs something in the 800+cfm range for the carb. needs 3" duals, and an 8" converter with a stall speed of 5000ish rpm. talk to Justin (Fast383) on here about a converter. he gives good deals to tgo members!

i wouldn't fill the block unless it was a track only car.

should work good aside from those moroso mufflers. they are terrible. if you look inside them you'll see what i mean.

true^^i picked up like .2 going from them to bullets, and they're about the same volume!

how much can i fil the block without cooling problems, id like to strengthen the block as much as i can. Im probably going to build a new 3" exhaust for is once my school is finished up in a few weeks.Iknow its not the best trans for the street, and i dont plan on hooking up the t-brake but its there if i ever want to try it out and i really want to put a tko600 into it cause i know im going to miss shifting it but the trans is just sitting in my garage and i dont have the money for a new tremec right now, and if i go with a 5000 stall will i still be able to drive it on the street regularly.
also im hopeing to go high 10s do you think that will be possible

put a tight converter in it, ~3.73 gears, nitrous kit, and set it up for running the bottle. this will allow you to run a 3200-3500 converter and a streetable gear ratio. would be a good cruiser and really haul at the track. besides, an all forged shortblock is way overkill for a n/a combo shifted at 6500.

i have a 9" with 4.11s all aftermarket suspension, im definitely going to spray atleast a 150 shot, the rings are being gaped for it. i went all forged because i got a good deal on the rotating assembly, only paid 1000$ for everything brand new , and if i want to go to a 421 later i can reuse the crank and rods

You don't need to fill the block for a high 10 sec car.

well if you plan to spray it, an 8" 5k converter would be a big mistake. you will want a 9/10" converter ~3500ish stall.

tru, but this engine combo/150 shot is good for low 9's in a well setup car.

check into a good oil cooler with a good fan setup ?
