just saying hi new to the forum

Looking for some help with my first build up of a BBC
just some questions about the parts I have selected
ok here it is for all to laugh

started with an 89 mark IV block 4 bolt main
stock crank, rods, and pistons
3904390 closed chamber heads
been decked to 95 cc
supposedly brings it to 10.25 cr
pocket ported and enlarged to 2.19 /1.88 valves manley ss
pete jackson gear drive
jones solid roller 708/710 lift 250/256 dur @.050
1 3/4 headers w/ flowmaster 40s
edelbrock performer rpm slightly opened
and a holley 750 double pump
msd billet dist and 6AL box


I think the ratins should be around 560 hp @6000 and 540 tq at 4500
if this is wrong or anyone sees any probs in my future please let me know before I fire this thing off thanks Jim
