170mphparachute

iTrader: (4)

88 mustang TH350 built up nice. I have alot of money into this motor and Im a little worried about hurting it. Its a pump gas motor and I have a seperate fuel system for the nitrous with 112 octane. The motor has a mild cam, the 2 pc intake and a 1050 dominator on it with a NOS plate kit. Ive been spraying a 125 shot to it but Id like to go a little more. What can I safely get away with. The motor has coated diamond forged pistons. Part # for the pistons is 11581.
Top Piston ring is a Plasma moly ductile w/ a .018 ring end gap
Second ring is a RBT Cast Iron with a .022 ring end gap
Oil ring is a Std Tension Hastings Style ring with a .018 gap
I rev the motor to 7000 rpm. The cam is a comp cams part # 54-000-11

595 lift intake/exhaust
248 intake
254 exhaust
110 lobe sep

Do you think I could safely spray a 150-175 shot to this motor on race gas and with the proper timing/fuel and plugs? Also, what NGK plug do you think I should use, maybe a TR7 or colder? Any help would be appreciated. I dont want to hurt this thing.

You can do a 175 I would go ahead and run a #8 plug to be safe and deduct the right about of timing. Its not worth hurting a motor for a cpl of tenths.

Usually the non-projected tip plugs are recommended. BR7EF, BR8EF, etc. Ill let someone a little more qualified make the suggestion as to what temp range.
