Mild Modifications / Re: The Hugger goes ZL-1....
« on: September 14, 2015, 08:21:34 PM »
I just finished my ZL-1 last week. I bought the same block, they are up to $5,200 now, I bought mine in March when they were 5k, I had a 10 percent coupon from autorama and it saved me $500.
The blue freeze plugs are the older ones, new are black. Make sure your engine builder checks the line bore, they had an issue in the past.
The 163 intake is the same as the 198, without the divider cut down. I found my 198 for $350. The correct 074 heads are $2,500 done, minimum.
I had pistons made by diamond with 11.5 compression to run on 93 octane, no issues at all. Mine made 550 with a solid cam and cast iron exhaust manifolds, headers are worth at least 50hp on this motor.
