now has 1970 400 standard rod / crank /pistons
1970 400 290HP 16(sm valve) 1.96/1.66 listed as 10 c.r.(thou ive been guessing it at about 9.25 as ive heard thats more accurate)
very mild port/cleanup
swirl polished valves/cc polish/clean
comp cam CCA-51-222-4 (XE262H) advertised Duration 262/270, Lift .462/.470 (also have summit 2082 cam in shed but told not so good and also looking at 275DEH?????)

mach 1 underdrive ALU crank pulley
3.08 gears/standard converter
and in uk we have 97-99 ron petrol

car interior is striped w no air con so expect car to be around 3700-3800lbs i think,is this a good guess????

what does everyone think of this combo??? is a car to be used for fun on weekend and down track
want to see around 350-380hp at fly and 420-460lbs torque roughfly and /or low-mid 13's on the 1/4

am i along the right line ???.i have dyno simed/drag simed/cam quested my life away and ahve been looking at similar setups here on py and think this is good and have been told the XE262H is very strong and torqey...cant convert the sm valve to big so don ask (cant afford)
about 1 month away from ordering the parts so i need to finalise my list
all sugestions welcome. thanks for the help
