It doesn’t help that the intake and exhaust have to go into and out of the same side of the head. Poor flow design straight from the factory. But we have to use what we’ve been dealt.
In 142 S had 100 hp with 2xSU. My old B20 (in this video) has stock A-cam and lower compression ratio. Horsepower is 92 whp so advertised horsepower would be in this (92*1,2=110). I hope a can get a lot more from my rebuild engine with K-cam and ported cylinderhead.
Hi, i have the same head on my 1969 volvo amazon. Is it the normal b20a head? From what i have seen it is a later type head from the 70's, with slightly bigger valves, is this true? It has those flat spots as well on the top that are not present on the 60's heads, and which are made to be drilled for injectors.
I had an Amazone -62 rebuild the engine. Planad topp, fullt portad, större ventiler, dubbla fjädrar, mahle kolvar, lättat svänghjul osv o dubbla weber45or....den gav ca 140-160hk....och så trumbromsar...livsfarliga... Den gick som ett skållat troll...1978......idag skulle den inte ha en suck mot nästan en vanlug bil
