Thanks Cranman. The rad is original. I have to wait till Tuesday for the rad man to come back to work, so I will go out & measure up a few things till then. I am looking for a 6-7 blade fan that can bolt directly to the pulley, giving me a bit more room. I think I should have put the strips that hold the rad in place before putting in the motor, allowing me to get a more accurate measurement. I guess we'll mark this one down as due to lack of experience. I hope I don't have to move the engine back.
Here's an email I got from one of our members :
OT, I am rebuilding a wood bug as well.The rad is back in its original location and it 4 in from the centre of rear axel to the inside face of the rad.You would want about 1 in.of clearance from fan to rad.Dont use an elec fan as it will not cool .I know a guy that tried that.I have a narrow ga steel bug that I put a 300 ford wi a c6 auto in it and I have heating issues with it. You want to stick with a 6 or seven blade fan to move air...if able get the largest diam damper pully you can find to speed up fan and water pump .Iwill try send you what I started with when I started this progect.Hope this helps.
It helps alot my friend. This is what I need, all the info I can get. Thanks again !!
Just another minor set back for OT.
